Hi @Matthew ,
Welcome to Q&A forum!
I tested it in my environment and didn't reproduce your situation. According to the error message you provided, it should be an issue with account permissions. Let’s do some troubleshooting:
Check whether the user account you are using to configure the RSS feed has the necessary permissions to access the feed. You can also try logging in with a different account to see if the issue persists.
Check whether the RSS feed itself is configured correctly. Make sure that the URL for the feed is correct and that the feed is accessible.
