Dynamics 365 Authentication failed

Good day

 

My app has been running for months but today all users are receiving the following error: "One or more of your connections may not be authenticated. Tap here to fix" - tapping does not do anything.

 

I am not finding anything online

 

All my connections have a status of 'Connected'. I think it is D365 connection that is the problem because if I remove any code related to one if its entities everything is working fine. I can access the connections and Entities in Power Apps but in the app it throws this error.

 

It is also worth noting that the data does eventually come through it is just exceptionally slow.

 

Please advise

Hello. I logged a support request with Microsoft and their suggested solutions were rather helpful.

 

In your Power App, if you go to 'Settings' > 'Advanced Settings', there are 2 options you should select:

 

  1. 'Explicit column selection' (allows PA to only select the columns from a data source it actually uses)
  2. 'Improve data source performance & CDS views'

These 2 options really helped me. They also mentioned that you should use the entities more often so it would trigger dynamics auto tuning.
