I can not connect self to the cloud

Hello!

I’ve installed self-hosted version, but I can’t register to the cloud:
“An error occured”.

I do not see any messages in the log.

I see in the cloud console my installation twice:
Rocket.Chat|rocketchat.mydomain|Community Edition|Registered|self-hosted||
Rocket.Chat|rocketchat.mydomain|Community Edition|Registered|self-hosted||

Can I remove them from the record? Is it necessary?
