Issues configuring Cloudflare Warp as an HTTP proxy

[juanqp07]

When I configure Cloudflare Warp as indicated in the wiki it doesn’t work and I get the error below. What can I do?
Error:

Looks like you're using separate compose file for each service. If you do that, you should figure out how to connect their network. Your stremthru container can't reach out to wrap container.

If you don't know how to do that, follow the guide at https://github.com/MunifTanjim/stremthru/wiki/Deployment. It tells you to use a single compose file.

I’m still getting the same thing, even though I put it in the same file.
