Server losing internet connectivity and recovering after a while

[jcarre]

Hello everyone,

I have been having some troubles that I'm unable to diagnose.

I host some services through nginx proxy manager and it's been working fine for the most part. The problem is that sometimes I'll lose all connectivity to it and everything will come back on its own after a while (1 hour or more).
While that happens I'm able to ping home through the Internet, but the ports that point to nginx show as closed (443 and 80). I'm also able to connect to one of the computers in my home network with teamviewer, so it's clear that I did not lose internet access.

Today that happened at around 11:00 and recovered the connectivity at around 12:45.

I was able to get to a computer and connect with teamviewer and the server was accessible in the home network, but the web ui was really slow and failed to load the docker tab.

 

Looking at the logs I'm unable to find any clue as to what is going on. Just a bunch of errors of docker apps unable to download images.

 

I have a 10gbe Mellanox card in the system. And I have it set it up so that it's the only up connection.

 

Is it the card resetting? How can I tell?

 

 

Thanks for the help!
