This looks like a configuration file aspect, not an issue with the code. It should be addressed via users mailing list. Anyhow, new mechanisms were added for handing manual branch management, this might not be actual, if yes, then mailing list is the appropriate for configuration file help.

For sake of completing here, the error message likely to be due to no websocket connection found.

I am going to close this one, if still the case of an issue with the code, open a new item with appropriate details.
