Not able to update or create custom connector



Whenever I try to update an existing custom connector or create a new custom connector it loads for a while and finally shows the following error : 

Client request aborted. Please see '' for more details.

Please find the screenshot in the attachment.


Let us know if you need any further info.


Thank you,





As mentioned in the link, companies may set firewalls or block their users from unknown domains or IP addresses, which can be one of the reason why you get this error.


Did you try creating the custom connector through postman collection? 

If it works through postman, then you can export the collection and import it when creating the custom connector.


F12 network trace can also help gather more information around what other errors are logged when you try creating the connector.

@pdheeraj ,


have you found solution for this?

I am also having this problem on updating my custom connector.




Dear @pdheeraj , @rohsh354 ,


I hardly believe, but the explanation about firewall blocking IP address, could be relevant.

Basically I managed to update my custom connector by:

  • Connecting to a terminal server 
  • The terminal server is in different location (even different continent), thus having different IP address
  • Login to powerapps from the browser in terminal server, and just update the connector.


Hopefully this helps others too.

I am getting the same issue updating connectors, in multiple different environments and networks. I cannot believe it is a firewall issue, because very occasionally it does work. I found unblocking 3rd party cookies to *, * and * helps a bit, but still getting issues most of the time.
