Confluence 6.9.0 Problems with Collaborative Editing

Question

Dear Community, I'm having problems with my Confluence 6.9.0 Server Installation on CentOS 7. There's an Apache 2.4 used as a reverse Proxy and DNS Termination Point. When I activate Collaborative Editing and try to edit a page, I'm always facing " The editor didn't load this time error when trying to edit a page" Error. I tried everything on https://confluence.atlassian.com/confkb/confluence-throws-the-editor-didn-t-load-this-time-error-when-trying-to-edit-a-page-840796639.html, but I'm not getting anywhere. When I'm trying the port, it's available - when I tested the firewall, the request went through. So nothing should be blocking WebSocket Connections .... Also for completion, I wanted to paste my Apache 2.4 config ... SSLEngine on SSLCertificateFile /etc/pki/tls/certs/confluence-domain.crt SSLCertificateKeyFile /etc/pki/tls/private/confluence-domain.key LogLevel alert rewrite:trace6 ErrorLog logs/confluence-domain-error_log CustomLog logs/confluence-domain-access_log common ServerName confluence-domain ProxyRequests Off ProxyPreserveHost On RewriteEngine On RewriteCond %{REQUEST_URI} !^/synchrony RewriteRule ^/(.*) http://confluence-server:8090/$1 [P] Require all granted ProxyPass /synchrony http://confluence-server:8091/sychrony Require all granted RewriteEngine on RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC] RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC] RewriteRule .* ws://confluence-server:8091%{REQUEST_URI} [P] ProxyPass / http://confluence-server:8090/ ProxyPassReverse / http://confluence-server:8090/

Thanks for your input! I tried your solution, but it returned also the timeout in my instance ....

I'm sorry! You were totally right. I changed my config according to the article and everything works now.

Consider the above answer as well but I don't think you need any of the Sychrony directives in 6.9.0. What happens if you comment out all of this: RewriteEngine On RewriteCond %{REQUEST_URI} !^/synchrony RewriteRule ^/(.*) http://confluence-server:8090/$1 [P] Require all granted ProxyPass /synchrony http://confluence-server:8091/sychrony Require all granted RewriteEngine on RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC] RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC] RewriteRule .* ws://confluence-server:8091%{REQUEST_URI} [P] I don't have any of that on 6.9.0 and it works great.
