Error 500 with custom connector

I have an "error 500" problem when I try to create a custom connector by using a postman collection.

In Postman my request works very well.

When I create the custom connector and did the "test" I had this message : 


"error": {
"code": 500,
"message": "The remote name could not be resolved: 'serv-pifl'",
"source": "",
"path": "forward-request",
"clientRequestId": "f3c56ae2-b736-43ca-80d8-4d28-b08fbf3a"


Can someone help me about this ?

"The remote name could not be resolved" error usually means the DNS server(s) currently in use by your router or computer have a problem. To solve this you need to configure your router and/or computer to use different DNS servers. 

  1. Click the Start Orb, then select Control Panel.
  2. Click on Network and Sharing Center.
  3. Click on your primary connection or Local Area Connection under Active Networks.
  4. Click the Properties button.
    Windows 7 may prompt you for permission to make network setting changes.
  5. Highlight 'Internet Protocol Version 4' and click Properties.
  6. Click the radio button 'Use the following DNS server addresses:' and type and in the Preferred DNS server and Alternate DNS server fields.
  7. Click OK button, then the Close button, then Close again. Finally, close the Network and Sharing Center window.
    At this point, we highly suggest that you flush your DNS resolver cache and web browser caches to ensure that your new configuration settings take effect.

Did you resolve this?

I am also having a 500 error with message "The remote name could not be resolved"


I don't know anything about DNS servers. Are there side effects to changing to the settings that you gave?

Or are there other possibilities for what is wrong with this error?
