Have you had flow connection expire? For example when your flow owners use MFA and it is time to re-authenticate?

Would you like to get alerted before you get to the Fix Connection situation?
PowerApps and Flow PowerShell might be able to help you.
(Get-AdminPowerAppConnection).Internal.properties
The above command gives you all your connections.

All your connections will show as connected except for the failed one. But we want to catch the problems before they happen.
To make sure that you only get the failed connections you could even go for something like this:
(Get-AdminPowerAppConnection -EnvironmentName "Default-c9bc0321-d7ee-4269-93cc-935cbfef6278").Internal.properties | Where { $_.statuses -like "*Error*"}
Once you’ve got the list of connections that need to be fixed, sending out an alert should be easy.
Ok, So I didn’t get to the BEFORE a connection expires but at least I can get fairly close to the connection having expired.
Using Power Automate instead
Would you like to use Power Automate instead of Powershell? Have a look at the following post:
Broken Connections Using Power Automate
Hi good morning. I used this powershell admin command with a service account but I didn’t get any values returned. Do you know why? Thanks!
What do you get if you run just:
Get-AdminPowerAppConnection
