Funny i was just typing this when I saw your message.
Everything went perfectly in sandbox , but now been trying since yesterday to do exact same setting sin prod, 3 times now and always the same issue: whenever I try to use the new externalSF DSO i get authentication failed.
This is just driving me crazy , as i double and triple check everything is exactly the same as in Sandbox.
Only 1 thing i noticed different, is when i create the DSO, it tries to create the Authentication providers on it’s own, and i see a an error message that goes away too quickly for me to read completely and copy it , but an error creating remote setting basically.
I tried creating it manually, that did not work, So i tried creating the authentication provider myself (not from the new DSO setup) and this time it creates the remote setting properly it seems, but still same issue.
And yes I would love to show you the public site anytime!
maybe we can have a quick screenshare so we can do both same time?
Let me know
