Changed from Premium to Standard now getting Authorization Failed

Peter Tyrrell 20

Please help - our API was using the Standard pricing tier. 2 months ago we changed to Premium. This morning I changed it back to Standard - now getting 401 on every request:

"error": {
        "code": "AuthorizationFailed",
        "message": "The client IP address '20.45.157.29' is not in the allowed caller IP address ranges specified in the workflow access control configuration."

I downgraded the pricing tier from Premium to Standard @8:00pm 18/8/2024 AEST with Microsoft Support on-call. The process took over 3 hours to complete. This is far longer than the 15-45 minutes estimate from Microsoft. However, everything worked correctly with no outage.

I think Microsoft should update their advice on the estimated time for upgrade/downgrade of pricing tiers.

@Peter Tyrrell Thanks for reaching out. It sounds like the issue is related to IP restrictions configured in your Logic App’s workflow settings. When you switch between pricing tiers, some settings might not carry over

Ensure that the IP address 20.45.157.29 is included in the allowed caller IP address ranges. Once you have added the IP address to the allowed caller IP address ranges, you should be able to make requests to the Logic App without receiving the "AuthorizationFailed" error.

do let me know incase of further queries, I would be happy to assist you.

Hi, thanks for your comment. Yes, I figured that out and updated the allowed IP address for the backend. However, it doesn't answer why the Service update did not complete. We are still on Premium and want to change the pricing tier to Standard. I have a Microsoft Engineer who will work with me out of hours.

Peter Tyrrell Thanks for the update. Glad that you were able to update the Ip address and you are unblocked

The downgrade took over 3 hours to complete - do not believe the 15-45 minutes estimate from Microsoft.
