Document Service is not available. Please contact support

Good day.
Please tell me what the problem might be.
I have two servers.
Is installed on one server ONLYOFFICE Groups.
On another server there is ONLYOFFICE Docs.
Everything works great on the local network.
But when I publish ONLYOFFICE on the Internet, I cannot edit documents, this error appears

Document Service is not available. Please contact support.

Tell me what I’m doing wrong.
