Error Message during Update to Rancher 1.5.10


at the moment I’m using the High Availabity Feature of Rancher with Two Host Server. On each Server i have the rancher/server docker container running with version 1.5.3. The Database is running on a different Server.

When I want to update on of these two server to version 1.5.10 I get the following error message:

No invocation found for error response with callId: 0 sent from [IP of the other rancher host server]:9345

At the moment i don’t know what to do, have somebody a solution or a hint for me what I can to?

Kind Regards
