Sweet! That seems to put me in the right direction. It tried to submit a request to the authorize URL, but sent a redirect URI something like this: https://example.com/oidc/callback in the request.
Is there a way for me to change this redirect URI to be just something like: https://example.com without the /oidc/callback in the URI?
I tried uncommenting and editing the line below, as well as restarting Hue but it made no difference.
If not, I will just have to tell the OAuth service we are using to change the redirect URI to https://example.com/oidc/callback to adhere to this issue, but wanted to see if you had any suggestions before doing that.
