cy.visit times out in Jenkins but works in local

[eeshdarthvader]

Hi,

I have been tasked with writing integration tests for my company's app. It's for testing Auth0 login flow.

We have hosted a custom domain in our infra to show auth0 login page.

dev-de.<company-domain>.com --> dev-auth0.<company-domain>.com (Cloudfront domain hosting auth0 origin)

This works in local system but in jenkins it never loads this custom domain.

I enabled Debug logs and it shows this error

We increased the timeout , but it did not help.

Does a basic test such as cy.visit() your company app work on CI?

[eeshdarthvader]

No it does not. It works locally.

Clearly the machine that hosts your Cypress tests can't access the custom domain/server that your Auth service lives in.
To debug this I would just try to ssh into your Jenkins CI machine and do some simple curl's to see what can be accessed and what not. Makes sense?
