You have created an RME agent to run jobs on another master. The remote Master goes down and is re-started but the RME agent status stays in 'ERRORS' even though it's Master is 'RUNNING'.
RME was not written to loop try to reestablish the connection. Currently if the RME agent is stopped and the remote goes down it stays in stopped. If it is running and the remote goes down it will go to ERRORS.
After the remote Master is re-started, stop and start the RME Agent within the GUI.
