There was a OS update to the servers and after that wasp is no longer working.
wasp is never getting a pid or even writing to the log at both the OC and cabi robots.
Release : 20.3
Component : UIM OPERATOR CONSOLE - WASP & CORE
resolved the problem by removing this line 'start_after = controller' from controller.cfg:
magic_key = h2UvQSt9BdxYiOlJBN5/cw==
start_after = controller
