Environment

5.2.2

Cause

This is likely because the RMQ PVCs were created in a previous failed attempt and now the passwords are out of sync.

If you don't set the RMQ credentials, they are auto-generated when the Portal Helm Chart is installed, the PVC persists after the Chart is uninstalled and will need to be removed manually.

Resolution

Do a clean install and then the following .

Env command in the pod’s terminal to get rabbitmq username and password
Then command rabbitmqctl change_password <USERNAME> <NEWPASSWORD>
Everything started working after that
