Error occured during Confluence Server space migration to Cloud

[Leos Vojir]

While selecting space to be migrated from Confluence Server to Cloud I've got an error message. It shows that migration assistant is unable to communicate with our server instance. This assistant is started right from the server, which is to be migrated and right on the Windows Server machine where the Confluence servrvice is running :-|

Does anyone have an idea what might be wrong?

Many thanks

Hi @Leos Vojir 

Make sure that from your server you are able to reach the Atlassian Cloud when migrating.

See the following documentation.
