Failing DNS resolution when connecting over Mobile network

Hello Everyone

When I am connected to my mobile phone network through a hotspot (My phone is on 4G LTE), all the containers start to fail dns resolution, although they can reach internet (ping works).

This does not happen and the resolution always succeeds as long as I am connected to my home or my work router via wifi.

I use the default network bridge created by lxd.

Can you please guide me through troubleshooting this problem ?

Edit: this happens with my podman containers too.
