I imagine your OpenVPN server is se up using IPv4 :
and this implies you have to use IPv4 to contact the WAN IP of your pfSense.
But .... your phone, does it have it's own IPv4 ?
I can image, since there are no more IPv4 to give to everybody (there are more Internet capable devices on the planet as there are aIPv4 addresses) that your phone has only a IPv6 ..... and that sucks, as you need to use IPv4.
So, your phone, does it have a IPv4 - your phone data carrier gave it an IPv4 (it did give an IPv6, I'm sure) ?Fast solution : on the pfSense side, it's time to activate the "dual stack", which means your pfSense can use = will be accessible over IPv4 and IPv6.
When that works, change the OpenVPN server so it can be accessed over IPv4 and IPv4, or just IPv6 :
and you'll be fine.
Btw : I'm presuming a lot as you didn't gave a lot of info.
