A clear and concise description of what the bug is.

Thanks for the bug report! Are you are running PeerCalls v4 (master branch) or v4? Can you reproduce this bug on https://peercalls.com/alpha if you're running v4?

[Sameer-hesta]

Actually I have set up this on ubuntu by git. I install node v8.17.0 and go go1.14.2. When I try to run this on the development by the command npm run start:watch I get the following error
[ wss] Error accepting websocket connection: failed to accept WebSocket connection: WebSocket protocol violation: Connection header "Keep-Alive" does not contain Upgrade

And on the browser, I am getting following error on the console

WebSocket failed: connection to 'wss://domain/ws/123/kknGxoDSfYpHNIJn4SlDT5' Error during WebSocket handshake: Unexpected response code: 426

I am using https Help will we appreciated

Are you running Peer Calls behind a proxy server?

Are you running Peer Calls behind a proxy server?

Yes I am using apache as a proxy server

[jeremija]

You need to ensure your proxy is configured to support websocket connections for Peer Calls.

I'm using nginx, and it has these settings:

        proxy_set_header Upgrade                          $http_upgrade;
        proxy_set_header Connection                       "upgrade";

You need to find an equivalent for Apache, possibly the wstunnel module.

Thank you but already enabled proxy_wstuneel

My proxy command like this in host file

*ProxyPreserveHost On
<Proxy >
Order allow,deny
Allow from all

ProxyPass / http://localhost:3000/ connectiontimeout=600 timeout=600 Keepalive=On
ProxyPassReverse / http://localhost:3000/
ProxyPass /wss2/ ws://domain:3000/
ProxyPassReverse /wss2/ ws://domain:3000/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

I also try to change ws path in src/client/ws/index.ts to wss://domain/wss2

But no luck

[jeremija]

Do you have HTTP 2 enabled?

[Sameer-hesta]

Yes

[jeremija]

Can you try disabling HTTP/2 for /ws path? There's an issue with a websocket library (or Golang) with websockets and HTTP/2: nhooyr/websocket#4

[Sameer-hesta]

Mate thank you for your response

I have modified apache config for WebSocket

RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
RewriteRule . ws://localhost:3000%{REQUEST_URI} [P]*

and thats it

Glad you were able to resolve it!
