Symptom
I cannot activate CloudLinux with a license I purchased from Plesk. I get error:
Error Message:
Maximum usage count of 1 reached
Error Class Code: 61
Error Class Info: Too many systems registered using this registration token
Cause
The licenses for CloudLinux are for 1 entitlement only. Each registered server takes one entitlement.
The error mentioned above might be shown due to one of the following reasons:
- you try to register several servers with one license;
- you reinstall CloudLinux on the same server, which causes the same server to be registered twice.
Resolution
You need to contact CloudLinux support directly to check your license and delete the unnecessary server details:

If you need to activate CloduLinux on several servers, purchase the corresponding number of licenses.
