Hi there!
It sounds like you've made great progress with setting up OpenVPN on your phone. Let's see if we can figure out why it's not working over cellular.
Here are a few suggestions to help debug the issue:
Check Cellular Network Settings: Some cellular networks have restrictions or issues with maintaining a data connection during a voice call. Ensure that your phone isn't trying to handle a call while connected to the VPN.
Disable IPv6: Sometimes, IPv6 can cause connectivity issues. Try disabling IPv6 on your phone and see if that resolves the problem2.
Firewall and Ports: Ensure that the necessary ports (1194 for UDP) are open on your firewall and not being blocked. You might need to check with your carrier if they block certain ports.
Stealth or Obfuscation: Some cellular networks might block VPN traffic. Using stealth or obfuscation settings in your OpenVPN configuration might help bypass these restrictions.
Restart Devices: Sometimes, simply restarting both your phone and the VPN server can resolve connectivity issues.
Check DNS Settings: Ensure that your DNS settings are correctly configured in your OpenVPN client. Sometimes, incorrect DNS settings can cause connectivity issues.
