"Cypress failed to verify that your server is running." on Linux with latest Cypress

[alex1701c]

Current behavior

I get the error "Cypress failed to verify that your server is running." on the console with component tests. I am using vite with react. The URL is http://localhost:5173.

After lots of trial and error, I came up with the following workaround in the cypress config:

export default defineConfig({
...
    env: {
...
    },
    hosts: { localhost: '127.0.0.1' },

This made it work on a RHEL8.8 server and on GithubActions based on UBI8 running in OpenShift. I am quite confused by this issue, especially because it work fine on my windows dev PC.

In any case I hope people having similar issues don't have to spend as much time debugging this as I did :D

Desired behavior

No response

Test code to reproduce

Launching normal component tests, test content doesn't matter.

Thanks for the workaround. This issue appeared for me when updating from Cypress 13.1 > 13.2. Using vue with webpack.

Cypress now reports "[webpack-dev-middleware] wait until bundle finished:" before attempting to reach a dev server. No retry attempts necessary.

Can confirm we are also having this issue using Cypress v13.6.3 with an Angular project.
We run our ci test suite using the cypress/schematic v2.5.1 inside the docker image cypress/included:13.6.3

Then we get: Cypress failed to verify that your server is running

When mapping localhost to the loopback in Cypress config, the issue is worked around.
