Next.js (webpack) hot module reloading does not work

[curiousercreative]

software versions

$ cat /etc/os-release
PRETTY_NAME="Pop!_OS 22.04 LTS"
$ node --version
v18.15.0
$ yarn tunnelmole -V
2.1.10
$ yarn next --version
Next.js v12.3.4

repro

1. yarn add tunnelmole
2. yarn next dev & yarn tunnelmole 3000
   ER/AR: tunnel seems to work, the Next.js app loads in browser
3. Make some arbitrary templating change (copy, remove a block of content, etc)
   ER: the tunneled app should update without a reload
   AR: tunneled app does not update until page is reloaded
   AR: Browser console error:

   Socket connection to 'wss://qmwe6k-ip-xx-xx-xx-xxx.tunnelmole.com/_next/webpack-hmr' failed: Error during WebSocket handshake: Unexpected response code: 404

I looked into WebSocket support in robbie-cahill/tunnelmole-service#6

nextjs 14 still not working with the websocket issue, is this being worked on?
