The Problem is the following: I could previously access the Linux Server via ssh without a problem on my local Windows10 machine. I was running a program that could possibly have crashed due to high cpu/Memory usage, and a few days later I could not reach the server anymore. (Error message: Connection timed out)
Since I could also not reach the server from another machine, I tried rebooting the server. I still could not access the server via my local machine (could also not ping it), I could however remote into a different Server via my local machine, and from there access the Linux server. So I know the server can currently be reached via ssh.
I also still can access other servers via ssh on my local machine, so it should also not be an issue with my ssh. I originally could reach the server only in a VPN. To my knowledge, nothing in my or the servers settings has changed. What I have tried so far:
All to no avail, and I have run out of ideas what else to try or what to google. Any more suggestion as to how I could troubleshoot further?
