After upgrade to iRedMail 1.3 and iRedAdmin-Pro 4.4 I'm not able to edit any account profile in iRedAdmin-Pro. When clicking on the name to edit, I'm getting error message:

Error: ConnectionError(ProtocolError('Connection aborted.', BadStatusLine('No status line received - the server has closed the connection',)),)

Editing anything else, e.g. Domains, Aliases, etc. works fine…

Thanks for the help!
