I find that part of my Power Automate cloud workflows can't trigger to run successfully with below error messages:

Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256
Failed to validate token: IDX10223: Lifetime validation failed. The token is expired. ValidTo (UTC): ''11/13/2024 9:35:31 AM', Current time (UTC): '5/16/2025 6:52:55 AM'.

But if I edit the Power Automate and save it directly without any changes, this Power Automate can trigger by user event and run with positive result. Why?

Here is some information for my Power Automate workflow setup:

1.) The trigger point of the Power Automate is "List Item created or updated" in a M365 SharePoint list.

2.) The Power Automate is created by a Azure account that should be changed password frequently in local AD Windows server.

3.) The local AD account will then synchronize to Azure AD.

4.) The error Power Automate may not be triggered by end user over few months and if the Power Automate turns off by the system automatically, we will turn it on again manually or by scheduled task without any saving.

Hi @AK-16050723-0

I have seen such issues happen when there are policies implemented on the tenant level that require users to change passwords frequently or else the authentication tokens are expired.

Below are a few work arounds you can implement:

1. If possible, get the account that is being used for the flows removed from the policy (just have MFA but without a requirement to change password frequently)

2. If the actions you are using in the flows can be achieved by using HTTP actions by calling direct api requests, you can configure service principals and use azure key vault to get the credential, authenticate and then use the token to call the action. (this would require you to re build the entire flow and certain actions/connectors may not have direct api requests exposed)

Hope this helps!
