Can you describe more what your setup is?

Ubuntu 17.10 I just did what's written in the readme... but it does not work and I don't know why.
I badly need this to remote debug a smart tv application..

Can you provide any logs from the proxy? Also check out my talk on this project.

Answer 7 · 2018-07-15T09:20:07.000Z

I explain... I wish to do what I usually do with "weinre" but using chrome devtools.
With weinre, I just add a <script src=....> tag to any html page and then I can debug the remote device accessing the page using a browser on my local machine.

If I undesrtood, devtools-backend should do the same... but I can't get it to work on Ubuntu 17.10

Could you tell me a step by step so I check what I do wrong or what is wrong in my system?

Have you solved the problem? Can you share the solution?

For future users (including myself): The issue is that the server leaks sockets, EMFILE is caused by too many files being opened. The solution is to add a handler for every path (*) that just does req.status(404).end() after registering the other paths in lib/index.js. This resolves the issue and makes the server work.
