Hello Alex,
Thanks for the information, in fact this issue it's usually solved by restarting the service, but in this case even by restarting the whole server the incoveneinte was maintained.
Tests were performed creating new services, but after a while we have the same situation,
I tried to reset the configuration, but it took 40 minutes and it didn't work. So I did a very similar process, backup the configuration, uninstall GeoEvent (check that the C:\Program Files\ArcGIS\ServerEvent files are deleted) and delete the zookeeper fodler in C:\arcgisserver\local\zookeeper; restart the server, then install the GeoEvent and load the previous configuration.
However, connectors was not displayed and services could not be edited also the status of services was unavailable (same issue).
The solution was eliminate the current services and create new ones from zero, now is working. We have a case with Esri Support, I hope find a solution or identify the reason of why this situation is present.
Regards.
