See screenshot attached
I re-enabled br2 in the network section of the interfaces, afterwards I was unable to access the antsle web interface due to anthilld getting shutdown. Trying to re-start the anthilld service showed the following errors.
I believe this might be a hardware issue, in the past I had tickets relating to br2 loosing its IP address.
Re-running the upgrade-antman script seemed to disable br2 and solve the issue with access, just means that I am unable to use br2 for anything.
