While registration of a source Plesk server via PCP > Migration Manager > Source Systems > Register Source System, the following error appears:

After performing system health checks, the wizard has detected the following issues:
1. An error occurred while trying to check the connection to the Plesk XML API on the server 'Source Server': .
2. The system could not check the license because of issues with the Plesk XML API. Please resolve the issues with the Plesk XML API and try again.


The Plesk server rejects requests from Management Node due to firewall rules configured.


Make sure that connections to the port 29443 are allowed on Plesk service nodes, and that Plesk service nodes are accessible from the Odin Automation management node. For more details check Preparing for Migration Guide.
