Hoping someone can shed some light over here

when connecting to my home vpn server over wifi, the log says "Contacting [xxx.xxx.xxx.xxx]:1194/TCP via TCPv4" and it connects fine.

However when i switch over to 5G and try to connect, the log says Contacting [2001:8004:xxxx:xxxx::xxxx:xxxx]:1194/TCP via TCPv4 and times out.

It uses ipv4 address when connecting on a wifi network but seems to try and connect using an ipv6 address when using cellular which is not in my config file and enters a timeout/retry cycle

What am i doing wrong?

Try to ping your server IP.

You could also try --proto udp4

I initially started with udp and it failed on both wifi and cellular but it must have been to another config.

I set it to TCP and it worked on wifi so i left it there and figured there would be another config to blame for the ipv6 address switching that was happening between the network sources

I changed it back to udp and it seems to work now
