Can’t connect GL-INET AR750S to openvpn client over my current wifi network. But if I hotspot my phone VPN connection works! I’ve removed any specific address in the log dumps below and replaced with “xxx” OpenVPN service is KeepSolid.

Is your current WiFi network a public network? Could it be blocking UDP traffic or blocking port 1194? Does Keepsolid support OpenVPN over TCP on port 80 or 443?

3

It is a public network. And it does force using port 1194 and TCP 443. I’m going to try their wireguard config to see if that works

4

Most places do not block TCP port 443. Can you try Keepsolid’s TCP based OpenVPN config file?

5

I don’t see any options to use TCP only :frowning:

6

I would check with Keepsolid support. Most VPN providers have separate .ovpn files for their TCP and UDP connections. Just get their TCP .ovpn config file and setup a new OpenVPN Configurations on your GL iNet router.

Please try to change the ovpn config line:

ping-exit 30

to

ping-restart 30
