Postman action freeze during the first api call

Hi everyone.

We’re experiencing a weird issue. We are testing our NetCore webservice with API test running with Postman. We use a github action we developed (GitHub - yeapAi/newboy-action: Newman tests launcher). For about 10 days, the Newman (the Postman tests runner) action freeze during the first api call to the webservice. No error, no log then the action is cancelled by the timeout.

We double checked everything (Postman api key, action yml, etc.). The tests runs perfectly on a node instance on a desktop computer.

Does anyone have any ideas ?
