I have debug logs and found that in the one that has stopped working the request is incomplete:
GET /sharing/rest/portals/self?f=json
The request in the other add the token:
GET /sharing/rest/portals/self?f=json&token=.....
Trying to determine if this is a problem on the AGOL side or FME side. Any ideas would be appreciated!
Also having the same issue on Desktop.
