For the sake of your community and the bugfix, I can have another remote session, as I already had a 2,5h session with your team. (I can disclose details on PM if you want to.) So at least the issue is known and shown to your tech team.
You could also share the SSH / shell commands that allow manually decryption as quick-fix to help your community here.
Do you still think we need this session? Is there a place where I can find and share log files first? This error should produce a log message somewhere...
