Redirect issue with Python 3 example api & oauth2 to local host

I have been using the github https://github.com/Panopto/panopto-api-python-examples folders cli with some code that worked fine from a remote desktop PC in our datacentre.

Having come back recently, that code no longer runs, nor does the sample.py code in the folders-cli folder work.

The browser (chrome) opens up the panopto website as usual, with a redirect to local_host, but the chrome browser never does the redirect to save the token.

The browser tab says "Error"

The api client I created had disappeared (I assume expired) so I create a new Server-side Web Application api client for the same user (who happens to be an administrator) but the I get the same error.

Has there been a change to chrome or the api to stop redirects to local_host? Or to web api's to admin users? Or am I off track?

The url is

Opening the browser for authorization: https://myserver.cloud.panopto.eu/Panopto/oauth2/connect/authorize?response_type=code&client_id=some-value&redirect_uri=http%3A%2F%2Flocalhost%3A9127%2Fredirect&scope=openid+api+offline_access&state=somecodevalue

HTTP server started at port 9127. Waiting for redirect.

The code then sits there and the only sign of error is the error in the browser tab

    Thanks - just to confirm what I had done was put the right redirect url onto the wrong client id.

    Tried the same setup in Postman using https://support.panopto.com/s/article/How-to-use-Postman-with-the-Panopto-REST-API

    Getting the same error

    Tried setting up a pure API client (not associated with a user) - same error

    Error is:

    Chrome browser opens up, browser tab says "Error", redirect doesn't appear to happen.

    So I set the redirect url to allowed https%3A%2F%2Foauth.pstmn.io%2Fv1%2Fcallback and https://oauth.pstmn.io/v1/Fcallback but still getting error in the browser tab

    Hi @Caitlin McCabe ,

    Still having this issue, the code examples don't work and open a browser tab with title "error".

    Sorry not to have fed the solution back.

    The API I had originally set up in Python didn't require a callback url, but after a gap of time when I ran the code again I hit this problem.

    In my case, writing from a PC with python, I noticed the API request had a callback url of


    To be safe I also added the url below


    That worked first time because I already had the credentials setup and working

    Your callback url may not be the same of course, but it should be findable

    Hi @Caitlin McCabe , still isn't working. Url was allready url encoded, so this isn't the issue. Been trying to use the api with postman now, there it does open the pop-up for authentication, but then I get a "Error: invalid_client" error for some reason.
