Suddenly, things aren't loading properly. For example Heimdall takes forever to load and Navidrome is timing out.
When I do docker-compose pull
It says says
Error response from daemon: Get "https://registry-1.docker.io/v2/" net/http: request cancelled while waiting for connection (Client.Timeout exceeded while awaiting headers)
I would try momentarily replacing the defined dns servers with nameserver 1.1.1.1 and see if stuff improves, though the pull error would hint that docker did resolve the name but somehow didn't get an answer.
Hard to guess what else could be a problem apart from some obvious stuff - check if the internet connection is healthy and stable (ping, watch for spikes in ms or drops, also any outgoing firewall filters?)
