client I downloaded the openvpn config from ivpn and imported it with nmcli but I had to manually input the ca cert and tsl cert

Its working 100% perfect on WiFi but when I go on 4g it connects to the VPN but I get no internet

I'm on ubuntu touch version 24.04.1.3

Perhaps could you try to reduce the MTU packet size?
nmcli connection modify "Your_VPN" +vpn.data "mssfix=1300"

Another possibility is to disable IPV6
nmcli connection modify "Your_VPN" ipv6.method ignore

[Privacy+freedom]

@Vlad-Nirky will try this

@Vlad-Nirky sadly non of those commands fixed it

Pretty weird that openvpn works on WiFi but not mobile data

@Privacy-freedom
Last chance, force the openvpn
nmcli connection modify "Your_VPN" ipv4.never-default no
nmcli connection modify "Your_VPN" ipv6.never-default no

@Privacy-freedom
Did you tried a ping of an IP address or a domain name?

[Privacy+freedom]

@Vlad-Nirky tried to ping google now i just get Temporary failure in name resolution
those commands did not fix it also

I was wondering if you could ping 8.8.8.8 instead of www.google.com
More likely a block by the ISP

[Privacy+freedom]

when i run ping 8.8.8.8 i get
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data
when i dissable vpn on 4g i get much more output when i ping

never heard of isp/carriers blocking vpns where i live might try a config with port 443 then.

443 i heard can often get around vpn blocks

@Vlad-Nirky tried a new config with TCP at port 443 same issue

I'm pretty sure my mobile data carrier doesn't block VPNs. On my old Android phone I used OpenVPN 24/7 when I was on 4G before I switched to using Ubuntu Touch as my daily driver.

i run vpn on my router so its really only for when im on 4g/mobile data i woude want a vpn on the phone
when im at home i get vpn over wireless
