We have recently been experiencing issues with nominet/.uk domain registrations. The domain cannot be registered because of the following error:
Register Domain; Domain DOMAIN.ORG.UK. Error occurred while registration. Error: 2201. Authorization error. V142 Account 126895A5FA2512D2 is not on your tag;
Account id (
126895A5FA2512D2) may be different.
The problem is fixed in PBA-S since version 4.5. Here is bug id:
PBAS-29135 - Account XXXXXXXXX is not on your tag
Consider upgrading PBA-S to verison 4.5 once it released.
To apply the hotfix to PBA-S 4.3 contact Parallels Support.
