Hi,

Have a good day. 

I also wrote in StackOverflow(https://stackoverflow.com/questions/62100214/why-i-am-getting-websocket-error-in-web-rtc-conference/62108597#62108597)

Please enable the following modules:

a2enmod proxy proxy_http proxy_wstunnel

Add the following lines in your conf file.

RewriteEngine on
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) ws://localhost:5080/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) http://localhost:5080/$1 [P,L]
ProxyPass / http://localhost:5080/
ProxyPassReverse / http://localhost:5080/


After that restart the apache2 services as below:

systemctl restart apache2

Best Regards,

Selim

Hi Ragesh

I changed some definitions in Apache reverse proxy and web socket configs. Please try as below.

RewriteEngine on
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) ws://localhost:5080/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) http://localhost:5080/$1 [P,L]
ProxyPass / http://localhost:5080/
ProxyPassReverse / http://localhost:5080/

 It worked in our test instance. ​I hope it helps.
