Philipp Zehnder commented on STREAMPIPES-461:
---------------------------------------------
Hi,
thanks for reporting the problem.
It seems that the worker executing the adapters is not able to communicate with
the backend. This is also the reason why the adapter shows up in the adapters
overview, but not in the pipeline editor.
When you start an adapter the backend initiates the adapter creation in the
worker, which then registers the newly created adapter in the backend. Can you
please check if the worker is able to connect to the backend? Therefore you can
log into the worker container and try to ping the backend.
