I am having trouble connecting to an external ArcGIS Server in GeoEvent 10.3.1
The URL is https://gis.aes.accuweather.com/arcgis
The connection is valid in GeoEvent 10.2.2
In GeoEvent 10.3.1 is there URL format-checking happening behind the scenes when connecting to an external ArcGIS Server? Could this be preventing us from saving the connection?
