I change the synchrony port in the setenv.sh file but confluence isn't showing the change

Question

I am running Confluence 6.6.0 behind NGINX and needed to change the default synchrony port.

In setenv.sh I added:

CATALINA_OPTS="-Dsynchrony.port=8092 ${CATALINA_OPTS}"

and in NGINX I added the following to the Configuration

}
    location /synchrony {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:8092/synchrony;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

However, when I turn on collaborative editing, pages cannot be edited.   I get "Something went wrong after loading the editor. Copy your unsaved changes and refresh the page to keep editing." and have to hit the back button to stop trying to edit the page. Any ideas?

Dear All

I have 2 confluences db installed on 1 windows server 2008. I need to open synchrony both 2 confluences. One is set port 8091 default, open Collaborative editing and it works. The second I turn on Collaborative editing , I cannot open page to edit, it errors:

"This page is taking longer to load than usual. Give it a few moments, then try refreshing. Still having issues? Contact your Confluence admin."

Would you please tell me how to change synchrony port so that we can use Collaborative editing in both confluence.

In setenv.sh I added: ( in the second confluence )

CATALINA_OPTS="-Dsynchrony.port=8092 ${CATALINA_OPTS}"

and restart service of confluence but it does not work

Many Thanks,

Yes, I restarted Confluence.  I used 8092 because the person who set up NGINX is using 8091 for another purpose.  It looks to me like it NGNIX is not set up to handle web socket connections. I have an incident with my IT staff to check on this - will keep you posted.
