Change Detection - Error on opening UI

[a-r-j-a-n]

Getting this error when opening the UI. Same via ingress or ip:port.

Installation was working flawless before. Looks like the detection jobs are running flawlessly as well in the logs.
Any clues why this happens?

Sorry, I do not actually use it. Let me know if it doesn't resolve. Probably an issue in the actual container.

Alex belguims addons also have a version, can try that one
