Fix agents on broken hostname/ip

Updating the Server

1. Pick a hostname
2. Setup DNS or /etc/hosts files so all agents can resolve the name
3. For HA: upgrade or reinstall helm chart with new hostname/certs. Docker Container: update contiainer with new certs (see upgrade instructions) or just use the default self-signed
4. Change the server-url setting to the new hostname (settings -> server-url)
