Issues in testing REST API using Cypress in corporate env

[anithiya]

I am working in a corporate environment. I need to test certain APIs using Cypress. The major challenge I have is I need to call APIs which require Client Certificates to be passed. However, the Client Certificates are not being detected by Cypress.

I followed the steps laid out to for configuring proxy as explained in: https://docs.cypress.io/guides/references/proxy-configuration#Set-a-proxy-on-Linux-or-macOS

I am able to test the UI using Cypress in our corporate env.

However, when testing with REST APIs, i followed the steps here to capture the ClientCertificates as our API use certs for auth.

https://docs.cypress.io/guides/references/client-certificates

But I get a timeout error:
`CypressError
cy.request() failed trying to load:

https://apiendpoint1.com:1234/v1/resourceName

We attempted to make an http request to this URL but the request failed without a response.

We received this error at the network level:

Error: Error establishing proxy connection. Response from server was: HTTP/1.1 503 Service Unavailable
Cache-Control: no-cache
Pragma: no-cache
