Fallback proxy doesn't work on Node v17+

[mirismaili]

Environment Versions

1. OS Type: Windows 11
2. Node version: 16.14.2 & 17.9.0 & 18.0.0 & 18.2.0
3. http-server version: 14.1.0

Steps to reproduce

http-server --proxy http://localhost:8080? doesn't redirect deep paths to the root.

I use NVM. When I switch to node.js v16.14.2 everything works well. But not on v17.9.0, v18.0.0 and v18.2.0.

Having a similar problem, but even trying node v16.14.2 doesnt solve it for me.
React SPA, home page and routes work fine, but browser refresh or deep linking fails.
Proxy functionality seems not to intercept, returning 404 instead.

PSA: I ended up using sirv-cli with the --single flag as a workaround.

[santiagovm]

Running into the same problem with http-server. Tried sirv-cli, but it did not work for me (does not play well when starting multiple web servers via node-foreman). Using browser-sync as workaround.

[nowaktomek]

As a workaround you can try using

http-server --proxy=http://127.0.0.1:8080/index.html?

or you can try

http-server --proxy=http://localhost:8080/index.html? -a=localhost

Messages from http-server output says:

Available on:
  https://127.0.0.1:8080
Unhandled requests will be served from: http://localhost:8080?
...
[2022-05-22T22:50:53.564Z]  "GET /en/org" Error (404): "connect ECONNREFUSED ::1:8080"

meaning that http-server is not listening on ipv6 address: ::1 but only on ipv4 127.0.0.1

[corydeppen]

This set of options finally worked for me while using Node 18:

http-server ./build -a localhost -P http://localhost:3002? -p 3002

Available on:
  http://localhost:3002
Unhandled requests will be served from: http://localhost:3002?

[MahdiZerara]

I am using Node v21 and this works fine for me:

http-server -o -p 8080 -P http://127.0.0.1:8080? ./dist

But this doesn't:

http-server -o -p 8080 -P https://127.0.0.1:8080? -c-1 -S -C ./certificate/cert.pem -K ./certificate/key.pem ./dist

It seems that there is an issue with the proxy when using https
