I am trying to connect my university server via OpenVPN Connect app but I am getting the error “TAP mode is not supported”

Below is the content of .ovpn

client

dev tap

proto udp

remote IP PORT

resolv-retry infinite

nobind

persist-key
persist-tun

ca ca.crt

comp-lzo

verb 3

auth-user-pass

reneg-sec *****

I tried to change the dev tap to dev tun but it did not work.

What are the possible solutions to this problem? I want to connect with my university network via mobile.
