CEF Remote Debugging seems to not be working

[kartikynwa]

I enabled remote cef debugging from Decky's developer menu and rebooted. But I cannot debug remotely for some reason. I got it to work the last time I had to use it but am struggling now.

The .cef-enable-remote-debugging file exists:

~ deck@ksdeck
❯ ls ~/.steam/steam/.cef-enable-remote-debugging
.rw-r--r-- 0 deck  1 Dec 21:20  /home/deck/.steam/steam/.cef-enable-remote-debugging

But no tabs show up on the inspect page:

Besides I don't think anything is being served on port 8081. Here is the sudo ss -ntlup output:

CEF debugging was running at 127.0.0.1:8080 so I couldn't access it remotely. I had to use socat to forward this port to 0.0.0.0:8081. After that I could access it remotely. Not sure if it is a bug or not but closing since my problem is solved.
