Connection established and then times out

Post by michelvdriel » Tue Mar 09, 2021 3:43 pm

I'm having some trouble with a VPN connection that we get in from one of our clients. This connection has been working without issue for over a year, but this morning it started giving trouble.
The client has a teltonika device that connects to our VPN server. All settings are unchanged on both this Teltonika device and our server. However, the server receives a connection, seems to complete the initialization and then after a minute (which is the time we set for this connection) times out due to no activity to start all over again. I really have no idea where to start troubleshooting this, especially since this was working perfectly and we did not change a thing.

This is the logfile for this particular connection on the server side. I don't have a log from the user's side as they are a few countries away and we don't have anyone near at the moment.

This server hosts a large number of vpn connections and they are all working, it is only this one that is giving us trouble.

I know this isn't to much info, but any guidance is much appreciated
