Cannot deploy new containers when using custom DNS

Today I reseted my proxmox server. The first thing I put back online was my adguard home DNS server. But when trying to deploy other containers I got an error message. I tried different containers but they all give the same as error message, namely

Error Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 127.0.0.53:53: read udp 127.0.0.1:49692->127.0.0.53:53: i/o timeout

So can anyone help me out what Is wrong, is it even a good idea to run AdGuard in a docker instance with other services on the same IP, or should i run a container or VM on my proxmox with its own IP only for running adguard.

Thanks
