      So I've been having this issue with my OpenVPN server for some time and its driving me insane to the point I suspect something funny is going on with my ISP or my mobile data provider…

      Problem: I cannot 95% of the time connect to my OpenVPN server from my iPhone using LTE using the OpenVPN connect app, I can however connect 100% of the time via WIFI on the LAN.

      I believe my openvpn config is sound as I can connect via wifi, I also believe port forwarding is sound as I can connect sometimes.

      Tonight I after many attempts (not changing anything, just trying to connect, I managed to connect) here is the log from the OpenVPN app.

      Note

      Currently only able to access via VPN but once I'm within the LAN I'll post configs but based on the fact it works flawlessly on the LAN I am to think its not the config.

      Any ideas on how to resolve?

      I'm using 2.2 BETA after upgrading from stable after thinking that may help. Guess it might have made it worse.
