I tried to make the modifications here but was still unable to connect. I also tried updating var wsproxyURL to be the webserver's DNS name.

combinedLibs.comb.js:372 Uncaught DOMException: Failed to execute 'insertRule' on 'CSSStyleSheet': The index provided (13) is larger than the maximum index (0).

commands I ran:

   509  8:42    git clone https://github.com/stuicey/SSHy.git   
   510  8:44    cd SSHy/
   511  8:46    git submodule update --init --recursive
   512  8:46    npm i -g wsproxy/
   513  8:46    wsproxy
   514  8:46    bg
   515  8:46    ls wsproxy/
   516  8:46    java -jar closure-compiler.jar --js_output_file=js/combinedLibs.comb.js js/defines.js js/src/*.js js/*.js 'wsproxy/.comb.js' 'wsproxy/Client.js'

Note command 516 was typed as java -jar closure-compiler.jar --js_output_file=js/combinedLibs.comb.js js/defines.js js/src/*.js js/*.js '!**.comb.js' '!**Client.js' however bash expanded the ! for some reason.

Changed the var wsproxyURL to be "wss://ssh.nightmare.haus" and now I get the following

combinedLibs.comb.js:372 Uncaught DOMException: Failed to execute 'insertRule' on 'CSSStyleSheet': The index provided (13) is larger than the maximum index (0).

Seems like it doesn't appreciate the 200 okay that it is sending?
