Random connectivity issues with OVH Proxmox node
Has anyone been experiencing random connectivity issues to Proxmox VE 6 node on OVH/SYS (or, anywhere for that matter)?
I have one server on SoYouStart with Proxmox 6 and it happens rather randomly that I cannot ssh to the machine or open its GUI (no server response). At the same time I can access all the VM's on it without any issue.
Also, if I had an ssh session active with the node at the moment of issue happening, the session will keep working as nothing has happened, but if I disconnect, I cannot ssh back.
I don't have a firewall active on the node. All the services keep working normally all the time, logs are not showing any issue (during the issue no connection attempt is being logged anywhere). SSH and 8006 (for the GUI) ports are open and listening all the time.
I have no clue where and what to look for.
Any idea appreciated.
The Proxmox itself is installed with the SYS provided image and is an as standard install as possible: no zfs, no ceph, no cluster. I have 4 HDD-s in a raid 10 configuration (software raid, option selected during the Proxmox installation). The first thing I did after installation was to register an ACME account and obtain a Let's Encrypt certificate for the domain where the node is. No LXC containers, just KVM. Cannot remember now if the issue started happening before creating the very first VM.
