System not working for the app store

[stlpedro]

System has been very unstable with a bunch of issues in the last couple of days. I just got in and saw that the dns resolution is not working...

Tried the other things in the forum but it still not working. This is prod so we need it back up as soon as possible.

Right, you need to figure why unbound is not starting. The logs are in journalctl -u unbound -fa . Note that if unbound doesn't work, DNS doesnt work properly on the server and makes this quite unstable (as you experienced already).
