      Just to be clear:
      Are you trying to install the OpenVPN server or the OpenVPN client on your phone?

        @Vlad-Nirky 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

                @Vlad-Nirky sadly non of those commands fixed it

                Pretty weird that openvpn works on WiFi but not mobile data

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

                    Did you tried a ping of an IP address or a domain name?

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

                          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

                              Any errors in
                              sudo journalctl -u NetworkManager -f
                              What gives ip route show when vpn is active (mentionning tun interface)?

                                when i run sudo journalctl -u NetworkManager -f
                                these are the only errors i noticed

                                Dnsmasq is just using nameservers and NetworkManager is bringing up tun0. The only real problem in the snippet is the VPN restarting:

                                nm-openvpn: Inactivity timeout (--ping-restart), restarting
                                nm-openvpn: SIGUSR1[soft,ping-restart] received, process restarting

                                this is the active connections listed when i run mnlci connection show --active

                                o1.gw.ivpn.net
                                NetCon
                                lo
                                tun0

                                  I restarted my OpenVPN (on Pi-hole).
                                  I was able to connect my phone to it and access my home network via 4G LTE.
                                  Running on 24.04-2.x (don't know if this matter)

                                      Yes not easy to share things without leaking some private informations...

                                      Perhaps could you take a look at this exchange

                                          @Vlad-Nirky thanks
                                          I anonymize the IP routes log but I quickly realized it woude baisicly be useless when anonymized

                                          So I just deleted it since it had no value
