cypress: Cypress hanging/stop with remote server (maybe https related)

Current behavior:

I am trying to run my tests with my staging server in https

I have recorded a video of the what exactly happens:

https://www.hippovideo.io/video/play/22oQrG8pRA_ShkNs1tXdzdjBu0b8r0Pw9aU_JNy-K9Q

Looks like it is redirecting to my domain and then stop without displaying any error.

Upon inspecting the console I have this error:

Refused to execute script from 'https://www.googletagmanager.com/gtag/js?id=CODE_ID' because its MIME type ('image/gif') is not executable.

This error appears also in my localhost but in this environment the tests are running flawlessly without problems.

Unfortunately I cannot check if the tests are actually working for http, therefore I am not sure this is a problem related only with https

Steps to reproduce:

this is my cypress.env.json:

{
  "baseUrl": "https://mydomainname.com"
}
