I have a Linksys LRT214 that I have OpenVPN setup and was working fine and then sometime within the last month I think just stopped working. I tried restarting the router. Did a firmware update as one was needed. Tried creating a new vpn client, nothing worked. Looking at the logs, I think its timing out on client waiting to hear back from server. But again, there have been no changes. Below is the client config and the client log. One other note, and I had to scold my client on, the room the equipment is in didn't have the AC on and the room had to be 90+ degrees for several days at least this past week, so maybe its possible something cooked on the router that deals with OpenVPN functionality?

Hi Cg,

"Server poll timeout" in client logs always means that the client transmitted the initial OpenVPN packet, but no reply was received. It almost always indicates a firewall issue of some sort. It could be on either side, client (perhaps the ISP or upstream router?) or server.

Assuming nothing was logged on the server side, your packets simply did not arrive there.

regards, rob0

That is what I thought. Thing is, there is no other firewall, just the built in one of the LRT214 router, and I tried disabling it, too when testing. And the issue is happening from multiple client locations. The Internet going to the router is Spectrum Business Fiber and far as I know they don't ever block anything to begin with. Might need to just swap the router out at this point.
