Hi,
I have an issue with JSM Project as I'm trying to grant access to users with no license.
Within the projects settings, I've added my personal e-mail address as a Service Desk Customer but it doesn't appear on the list of people:

I received an email (to my private address) inviting me to join the team but as I'm clicking on the link, the following error appears:

The same for me trying to access the Portal directly from the link.
I read the documentation, tried to fix my permissions, etc but nothing seems to work.
Is anybody able to help me figure this out?
Thanks in advance!
