Error "Bad Gateway" Error 502 - Flow was running fine

I've created a PowerApp that uses flow to submit a simple form to a SP List. It was working fine but now I am getting a 502 Bad Gateway Error. Any Ideas?

Hi @Jake-Harvey,


Would it be convenient for you to share the Flow running details in a screenshot?

Troubleshooting a flow

In addition, please check your connection settings under Microsoft Flow Connection page:

Manage connections in Microsoft Flow

For another try, delete the SharePoint action and then add it again to check out.

Same here, have had a number of flows running perfectly well until the end of last week. Very frustrating!


Not sure if it is due to Microsoft, internal servers, my flows or something else.


Has anyone had any luck with this?

I just realized that one of the flows I created, to add a 'Due Date' in a column based on the created date, has failed numerous times -- error being 'Bad Gateway'.  After selecting 'Resubmit', it functioned as intended.  However, for all the entries that were input prior to today, the column was never updated with the calculated date.  


I have another Flow that failed repeatedly after first running as intended.  Once I went in, opened the Flow in edit mode and resaved, it started working again.  


As I promote the features of Flow and implementation of the application, these continued issues make it a challenge.  Can you advise -- is this a system problem and is it being addressed?  If so, what should we users expect in regards to performace and stability?

Generally I've found this issue occours when you are tring to have the flow update the Sharepoint list when the destination is unable to accept the flow's output. 


In my own issues with this error the flow has tried to submit more than the number of characters that can be had in a single line of text in a sharepoint list.
