Can't connect to Virmach VPS through home internet anymore
My Virmach DALZ008 VPS is up and running fine for last few weeks, however starting yesterday I can no longer access it from my home internet. Anyone tell me what is most likely going on here?
The VPS is online and the Virmach billing control panel, SolusVM control panel, VNC are all working normally.
From home internet it now always times out:

You have most likely banned yourself with your firewall script or fail2ban.
Search the iptables and ip6tables rules for a match with CSF:
csf -g [IP.add.re.ss]Search for IP address in fail2ban.log:
cat /var/log/fail2ban.log | grep "IP.add.re.ss"etc.
Thanks @kasodk . I've checked IP tables and Fail2ban log previously. I've also tried connecting from three different IP address (all Comcast cable IPs) with no changes. Other things have tried are rebooting computer, rebooting cable modem, flushing DNS cache, trying 3 different computers, and connecting through neighbor's internet.
I also have a purple daddy VPS out in California and it CAN ping the Virmach Dallas VPS too. It seems only local Comcast IPs won't connect.
This issue seems bizarre to me... Don't want to open a ticket because I know Virmach support is crazy busy at the moment and it's a Black Friday/no support VPS- and technically it IS online. Usually when weird problems happen with my VPSs it turns out to be something I've done on my end but have tried very hard to eliminate all the variables.
Was hoping someone could look at the traceroute IP info and say "THIS is what is happening" but guess it's not going to be that easy.
I'm not a networking guru or anything so I could be wrong here but if you can't reach the neighboring IPs as well, then it's safe to say it's not your VPS specifically, but most probably some Comcast ranges or
AS7922is getting blocked/filtered by their upstream for some reason(s).Looks like it's VPN time.
It wisnae me! A big boy done it and ran away.

Windows traceroute and unix traceroute work a little differently. Windows by default will send ICMP ehco request packets in the trace, unix will use UDP messages. Is it possible ICMP messages somewhere near your target destination are being filtered?
Dataplane.org's current server hosting provider list
@jtk @TheDP Don't really have enough networking knowledge regarding ICMP messages etc. but at this point I also think it's likely something is being filtered or routed incorrectly by someone
@AlwaysSkint I just downloaded Opera web browser because it has free VPN service and WAS able to connect to my Dallas Virmach VPS Virtualmin control panel. Usually very slow and many time out / tunnel errors and reloading, but it did connect. I'm on the east coast USA and for some reason choosing a European based VPN IP worked more reliably than choosing a local US VPN IP address
At this point unless I get some different info am going to assume this issue has nothing to do with my VPS configuration or any thing under my control. If it doesn't start working again in a week or two will try reinstalling the OS but don't see how that will solve anything. Currently don't have any live websites on it which is a good thing because at least part of the country wouldn't be able to access them anyway
Not going to tag him but - Mr. Vir Mach if you read this please let me know your thoughts.
Can you reach/trace the other IPs within the same subnet of your VPS’s IP?
Just pick some random IPs before or after yours.
If you can, then it’s your node.
But if you can’t, it’s most likely not your node, but something for VirMach and their upstream (DediPath?) to look into.
I just tried the 10 IP address directly preceding my IP and the 10 directly after it. My method was to type the full IP into Chrome browser address bar and hit enter. If this isn't a good way to check please let me know
All 20 timed out, no connection
Some odd routing there; from your VPS it bounces around cogent before getting down to dedipath's DAL border, but from your home connection it goes into their NYJ border and then gets lost. Might be something up with their routing?
Reminder: VirMach has Looking Glass in Dallas (and almost all locations) now: https://billing.virmach.com/index.php?rp=/knowledgebase/11/Test-IP-and-Looking-Glass-Locations.html&language=english
Probably worth to test if you can access lg and lg routes
Haven't bought a single service in VirMach Great Ryzen 2022 - 2023 Flash Sale.

Most likely scenario, IMHumbleO. When I was daft enough to have a server in LA (different provider), there were some funky routes at times. A routing table gone fubar.
Virmach did mention an issue with Dallas at some point, hence me migrating one VPS to SEA - along with another reason.

edit: removed wrong info
Many servers are not used for web hosting, so use traceroute or ping instead.
Blimey that was rapid, from the UK:

Didn't think of that. Just repeated the test of the closest 20 IP address using ping, all 100% loss/no connections
Then read this again:
https://lowendspirit.com/discussion/comment/99503#Comment_99503
Done a test from OVH (East Coast):
Completed fine, once the OVH network got its act together. It does appear to me that it's a hiccup at ASN 35913
Can you shed some light, @Virmach? (If not sleeping!)

Is this Comcast? They intercept ports 80 and 443 of my Buffalo VPS but I can still ssh. Apparently that server's IP range is in some kind of scam of phishing blacklist.
The 45.42.215.* subnet is blacklisted by @jarland.
Use the PDiddy vps to ssh into Virmach Dallas. Why lost sleep over this trivial matter?
Mods: Title may need editing. If Provider is not at fault here, why does title mention their name?
OP begins with Virmach, then ends up with Jarland. Mentions PDiddy for good measure. Only 53 more names to go

This is stupid.
It is a Virmach VPS and the subnet is blacklisted at mxrbl.com (run by mxroute.com).
Both providers are relevant to OP's problem.
Stupid is you.
OP pays Virmach for a service, can raise a ticket 🎟️ optionally for a price, since BF deal and all… but OP looks for free consultation here instead. and and here we are, making asinine comments .

No, you are making stupid accusations and asinine comments.
The rest of us have tried to help.
The PMS is high on this one. Taking a look back at the conversation:
-OP using Windows from home machine? Local machine firewall blocking for some reason?
- What is the VPS used for? Was any process / application being run that set off a few alarms?
- LG for Virmach Dallas is a 172 block, OP VPS appears to be a 45 block/ not sure how LG will be helpful in this case
- Biggest issue of all- why is OP NOT raising a ticket with @Virmach? Something preventing them from doing so? If so, what is? Inertia is a fairly innocent answer, but that may be wishful thinking.
- If the VPS subnet is blacklisted by MXRoute, what is the relevance/ significance to OP? Are they running a mail server? Does Crapcast follow the MXRoute Blacklists (do they use that term anymore - Crapcast? Used to be popular when I was their customer)
- Oh forgot this one- since I was labelled as making "stupid" accusations. I used to be a MaxKVM customer, so by extension I cannot be stupid. Look back at the messages. OP has left out enough details to raise flags. Prudent behaviour if considered asinine, is okay- mindlessly assuming provided information by OP is accurate, is not.

That !X doesn't seem fine to me.
@Janevski By "fine" I mean it's currently working for me as in sending daily backups of my website to the Dallas DAZ008 machine. And also I can ping Dallas from it and I can't from home. And traceroute does not time out. If there are issues with the connection between the two VPS doesn't seem to be causing problems for me at least in this instance.
Don't know what the !X means in the trace, that's why I came here for help free consultation
At this point am going to guess AlwaysSkint's suggestion of FUBARed routing table is most likely with Comcast blocking access as runner up. Time will tell.
edit: typo
We've had some really strange issues with our internet (Comcast) recently at the office here. At the same time when I was looking into what was going on with QN Los Angeles and Dedipath Los Angeles, I noticed the same weird thing going on for Dallas. We had a network engineer at QN confirm various things for us and it looked like it wasn't any issue with the networking equipment and then it started being fine again without any intervention.
But there definitely was something up with it at least to our office and a few other test servers and at the same time. And it looked similar to what OP posted, plus it was in a similar timeframe.
Speaking of which I'm not saying this is your issue but if you did that, and this was going to be my second guess, the system might block you. I was going to ask you if you had done anything like that but now we know you definitely did it afterward if you didn't do it before so there's a likelihood that you're blocked until it drops it.
Okay good thing you pointed that out, initially I scrolled past it and didn't notice. This means potential firewall issue. More specifically, it's icmp-host-prohibited.
Private message me your IP, your service's IP, and your other one as well. I"ll check to make sure it's not on our end.
One final issue it could be and honestly I'm going to bet on this one based on everything else I just said, is that maybe SolusVM glitched out when assigning the IP address to you or at some point in time and if any rules were reloaded, especially as a part of me taking a look at Dallas and LAX as I mentioned, it could mean that your service would effectively get blocked from using that IP address as part of SolusVM's protection. And maybe that IP address is pointing towards another VPS now and you just got banned for too many failed login attempts and that way the other VM could also easily have that icmp-host-prohibited rule as that's not uncommon.
(edit) But nevermind then it wouldn't make sense that you couldn't ping the others. It has to be a combo.
Reading Virmach’s wall of text above, it is evident that wht should have been a ticket 🎟️ from OP to Virmach, will now be addressed via PM, so still a 1:1 that the “helpers “ and “advisers” will not be privy to, unless shared by OP or Virmach with OP permission.
Paying customer resolving 1:1 with services provider who is recipient of payment. Which was my point.
Now who should feel stupid?
Have a nice day
