What kind of error did it show? Did you install/accept the Certificate?
Hello Morakot,
I am having this exact same issue after upgrading my ArcGIS Server, Web Adaptor and GeoEvent Processor from 10.2.1 to 10.3. I have verified the server account has appropriate permissions to write to the folders, but the licensechecker response is not getting written to the karaf file in the geoevent/data/log folder. This is the response I get when I try to open the GeoEvent Manager:
Minfin,
GeoEvent runs its own server, this is why it doesn't use port 6080. If there is nothing listening on port 6143 when you hit https://localhost:6143/geoevent/manager/index.html after starting the GeoEvent service, chances are the license you've installed is not valid. Look in the log file GEO_EVENT_INSTALLDIR\data\log\karaf.log and look for a line with contents "License status: GeoEventProcessor." That line will tell you if the license is valid or invalid.
