https://localhost/peerjs returns the expected JSON

Any attempt to hoist a peerjs connection fails.

https://localhost/peerjs responds with

https://localhost/peerjs/id responds with a 404

[CuAnnan]

I've tried giving it the path /peerjs in both front and back end, but it results in identical behaviour.

Which makes it look like router is taking over and not respecting app.use('/peerjs', peer);

I've tried moving it up and down, but to no avail.

[CuAnnan]

With the code as it is, if I try to set the path in the front end to /peerjs, before I get to the current error, wss://localhost/peerjs/peerjs?key=peerjs&id=ZNfSEBbys&token=d9krdtoczq8 returns a 404

If I set the path on the back end to /rtc, then the URI localhost https://localhost/peerjs/rtc/ resolves and returns the expected JSON
but the WSS request wss://localhost/peerjs/rtc/peerjs?key=peerjs&id=ZNfSEBbys&token=506gn78m2y5 fails with a 404

The body of the 404, provided by node, is

I went through most of the trouble that you have and ended up with this combination not producing the error, may be it will help you to take a look at it here.
