I get an error with evaluation code

With YaST:
Registration server error.
Retry registration later.
Details: Validation failed: Uuid should be formatted as UUID

From CLI:
sles12:~/Desktop # SUSEConnect -r A925********88 -e myname@mailserver.com
Error: SCC returned 'Validation failed: Uuid should be formatted as UUID' (500)

And it doesn't matter what do I use - login or email.
The evaluation code I get from customer center, subscription is already there.

I tried clean install, but attempt to register during install brings the same error.
