Problem connecting to server - Server poll timeout
-
Hello,
At more than 24 hours I can't connect to my server (raspberry pi + openvpn). Always worked without problems, but now I can not connect. Basically, from mobile data i'm connecting without problems, but through wifi my company can't connecting since yesterday (use fortinet firewall).
Initially I thought it might have been the port in 1194 blocked on firewall, but I changed my server settings for multiple ports and still don't get connect. At this point and to avoid this problem, I have configured the port 443, but doesn't work: "Server poll timeout, trying next remote entry…"Inside my company, I can ping to my server.
Does anyone know what could be?
