How to hande Error: getaddrinfo EAI_AGAIN

Hello everyone ! I’m facing an issue because of the change of my requests {{host}}. The new ending of this paramater is .nip.io. Since this change, all my requests fail with the message Error : getaddrinfo EAI_AGAIN

I don’t know how to solve this, The problem seems to be specific to postman (i tried the same request on insomnia and it worked fine).

My devops told me to change my test framework (quit postman) but I want to be sure that it is necessary

Thanks for your attention
