The radio is now operational, my best guess is, Ubuntu have released updates that affect the rolling and stable releaes of Azuracast. For this reason, I have rolled back to Ubuntu 18.04.6 LTS instead of 20.04.3 This fixes everything.

GC clients who have Azuracast installs, will not have release upgrades applied (system and security updates still will be applied) as this will more then likely break their radio.

Identical issue reported here on Azuracast Github
