There are several users with corporate proxy issues that are faced at several layers of interacting with Cypress including during:

Current workarounds:

Setting environment variables

Note: these are NOT cypress environment variables, but system/shell environment variables

  • If using Linux, you can read about setting and reading env variables here
  • If using Windows, you can read about setting and reading env variables here

Set HTTP_PROXY and/or HTTPS_PROXY to your corporate proxy

HTTP_PROXY=http://my-proxy-address cypress run

Set NO_PROXY for localhost to prevent it from hitting corporate proxy

NO_PROXY=localhost cypress run

Other workarounds

For cy.visit()

For Download

For accessing 'Runs' tab in Test Runner

  • If you need to set up a project, you have to do it in this tab. Fortunately, you should only need to do this once. Try to do this once outside of the corporate proxy then you should be good to go.

Tried setting env using cross-env HTTPS_PROXY=<my corp proxy> as well as HTTP_PROXY, but request to external resource gets http 407. I am using cntlm and set proxy to go through cntlm, but still unable to get CDN resources, e.g. google fonts

Tried do this:

PROXY_HTTP="http://proxy.adress" PROXY_HTTPS="https://proxy.adress" npx cypress run --spec cypress/integration/ah-ui.js -b chrome

With electron too, added rules in extension, add extension with VPN, added proxy settings in chrome...
but it doesn't work for me - best result - I can open url in new tab.
In Cypress test I receive -

CypressError: cy.visit() failed trying to load:


The content-type of the response we received from your web server was:

  > null

This was considered a failure because responses must have content-type: 'text/html'

I've read everything I can find on this issue and tried every suggested workaround but Cypress still cannot connect to websites through our corporate proxy.

When will this feature be implemented? It is a massive blocker for any possibility of adoption within our team.

Did you try to set the corporate proxy into npm config? Like so:
