GraphQL request works in Insomnia but not Postman

I’m trying to run a simple request via Postman with the GraphQL body type selected and got a 403 error along with these suggestions. Postman (which I’ve used before at other jobs) will be the better choice for automated testing, but my team usually uses Insomnia for manual testing, so my first debugging step was to see if what I was doing worked in Insomnia, and it was fine. That seems to rule out the first possibility that the server could not send a response.
I also just put in the URL itself and the actual Bearer Token to rule out errors in creating variables.

I went through all of the other steps below, but I’m not really using a proxy and the timeout was already set to 0 for infinity in the settings of Postman.

Has anyone else run into this? How did you resolve it?

Could not get any response
There was an error connecting to (the url, redacted from this post)
Why this might have happened:
The server couldn’t send a response:
Ensure that the backend is working properly
Self-signed SSL certificates are being blocked:
Fix this by turning off ‘SSL certificate verification’ in Settings > General
Proxy configured incorrectly
Ensure that proxy is configured correctly in Settings > Proxy
Request timeout:
Change request timeout in Settings > General

Can you please attach a screenshot with your error?

It seems that you have included some conflicting information, like getting a 403 error and getting no response.

I was able to solve it.
