Hi @Mark2AtSafe, @RylanAtSafe

Having trouble authorizing FME Server (FME Server 2017.0 - Build 17259 - win64) for use with ArcGIS Online. The FMEServer instance is part of a private network, therefore I have followed examples including those at:

1. https://knowledge.safe.com/questions/43567/arcgis-online-oauth-authorize-issue-on-fme-server.html
2. https://knowledge.safe.com/questions/65076/connecting-to-arcgis-online-via-fme-server.html
3. https://knowledge.safe.com/articles/40215/configuring-fme-server-to-use-oauth-based-web-conn.html

I have done the following:

• The FMEServer has been enabled for HTTPS
• The service account under which FMEServer runs on the server has necessary proxy whitelisting to hit the AGOL domains
• Since the FMEServer is private, it is not accessible publicly, nor has a public DNS entry. So as per the example in (3) I have set up a nip.io redirect to the IP address of the 'private' FMEServer
• I've got a registered application in AGOL (so got a clientId, clientSecret etc).
• The redirect URL has been set up in both AGOL and on the FME Server.

FME Server ESRI ArcGIS Online Config:

ArcGIS Online Redirect Config:

But when I go to authorize in FME Server it still returns.... :(

Any more ideas????

Much appreciated
