Issue Fetch configuration data from Plesk servers stucks

[EnriqueR]

I am trying to migrate some subscriptions from a Plesk server with CentOs 6 to another with CentOs 8, but it gets stuck in step 'Fetch configuration data from Plesk servers' and never finish. All Plesk are updated to the latest version.

If I want to eliminate this migration I have to restart the server because it does not leave me any other way. But when I try to migrate again, the same result always happens to me.

The constant message that appears in panel.log file is the following. Can someone help me?

ERR [panel] Forgery protection token check failed.
