Additional details
Prior to sending the API request to create a run, Cypress attempts to determine how best to make requests to the Cypress Cloud via a "preflight" request. This request is first made without the
CombinedAgentthat supports HTTP/S proxies, to one API domain. If this request fails, the second request is made to a different API domain, and uses theCombinedAgentthat uses proxy information in theHTTP_PROXY/HTTPS_PROXYenvironment variable.This is done to accommodate a wide variety of network configurations.
For network configurations that block non-proxied requests to the Cypress Cloud API, the request to create a run will always carry a 60 second overhead. However, this initial request is important to determine the network capabilities of the machine that is running the tests.
With this PR, the
CYPRESS_INTERNAL_INITIAL_PREFLIGHT_TIMEOUTenvironment variable can be set. This can be reduced below the default 60 seconds to trim the overhead. This environment variable can also be set to -1, which will disable the non-proxied preflight request.Steps to test
