Session time out Click here to log into Eclwatch goes to port 80

I've noticed in AKS deployments where we have https+DNS, when my session times out and I get taken to the page that says:

Authentication failed: invalid session. Please click here to log into ECL Watch.

When I click on the "Please click here to log into ECL Watch" it redirects me back to login with :80 (port 80) appended to the URL which it is not listening on, so it breaks.

As an example, for us-fcrathor-dev, it redirects to:
https://eclwatch.us-fcrathor-dev.azure.lnrsg.io:80/
