I have installed and successfully authorized the GeoEvent Extension 10.3.1 on my federated ArcGIS system (Server 10.3.1 federated and hosted with Portal 10.3.1). When I try to login with portal administrator username and password, I get an error that says the username or password you've entered is incorrect. I used Chrome developer tools to see what was happening, and noticed there is a missing trailing slash in the POST request to generate the token.
This is the URL for the POST request taken from Chrome developer tools (the POST requests returns a 404):
My Portal entry point is https://mygiswebadaptor.org.tld/gis, and the correct page for generating a token should be https://mygiswebadaptor.org.tld/gis/sharing/generateToken, but as you can see the proxy request omits the slash after gis so the page requested is /gissharing/generateToken (which doesn't exist).
Any way to fix this?
