Recently, I was added to a new organization. However, when I try to access its Confluence site, it gets stuck in a loading loop for about two minutes and then displays the following error:

In english it says:
You're almost there!
It looks like our database is taking a bit longer than usual to sync. Please wait a moment and try again.
If you keep seeing this error, please create a support request.
My account is also part of another organization, and I can access its Confluence without any issues. The problem only occurs with Confluence in the new organization — I am able to access the other Atlassian services in both organizations without any problems.
