I am using the terminado and i am running the unique.py inside the demo folder on port 9090 from inside a docker container with a ip of 172.17.0.2

So i have set up a reverse proxy using apache2:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName  terminal.local
    ServerAlias terminal.kide
    DocumentRoot /home/satnam-sandhu/Workstation/virtualhost
    <Directory />
        Options -Indexes +FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>
    ProxyPreserveHost On
    ProxyVia Full
    <Proxy *>
          Require all granted
    </Proxy>
       ProxyPass / http://172.17.0.2:9090/
       ProxyPassReverse /  http://172.17.0.2:9090/
       ErrorLog /var/log/apache2/local.kide-error.log
       LogLevel error
       CustomLog /var/log/apache2/local.kide-access.log combined
</VirtualHost>

when i accesshttp://terminal.local from my browser it get this error:

WebSocket connection to 'ws://terminal.local/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400

What am i supposed to do?

Here is the error log:

  • Did you look at your Apache logfiles? They will explain why you got HTTP error code `400`. – Patrick Mevzek Jun 25 '18 at 15:25
  • i have included the error log in the question, sir. – Satnam Sandhu Jun 26 '18 at 07:42
  • Connection refused: AH00957 looks like a good start to search for. however this might not even be the first request as the worker seems to have been disabled after it. Please add the first request (or wait at least 1min so the worker is back online, and verify that it actually is) when you try to connect. – Dennis Nolte Jun 26 '18 at 07:56
