Error: Web alias <domain>.xyz exists

Hi all!
Problems in adding .XYZ domain names by button «Add Web Domain» inside the Panel with «Error: Web alias {domain}.xyz exists». But it’s not exists, and wasn’t added in the past. Maybe not only with .XYZ domains.

Please run v-search-object {domain}.xyz

[email protected]:~# v-search-object {domain}.xyz
USER     TYPE  KEY  RESULT  ALIAS
------

Nothing.

Other domains (which was added w/o errors) respond normally, like:
[email protected]:~# v-search-object {domain}.com
USER TYPE KEY RESULT ALIAS
------
user web DOMAIN {domain}.com www.{domain}.com
