Apache Load Balancer not loading Confluence CSS

[Pranjal Shukla]

I am configuring Confluence DC with Apache Load Balancer. I have followed steps mentioned in this link. I have omitted settings of Synchrony as we are not using collaborative editing.

Upon accessing the LB URL, Confluence page loads but the CSS doesn't. It even redirects the requests to different nodes under the cluster. However, upon accessing the URL directly i.e. via Tomcat with port, the CSS loads properly.

@Pranjal Shukla  Welcome to the community!

Are you facing this issue for other type of resources also? like JS, and Images.

No, only with CSS. Here is my configuration:

<VirtualHost *:80>

    ServerName abc.xyz.com

        CustomLog "/var/log/apache2/confluence-http_access.log" combined

        ErrorLog "/var/log/apache2/confluence-http_error.log"

    <Location /balancer-manager>

        SetHandler balancer-manager

        Require all granted

    </Location>

    # Main Confluence balancer

    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED

    <Proxy "balancer://confluence-cluster/">

        BalancerMember "http://abc.xyz.com:8090/confluence" route=1

        BalancerMember "http://pqr.xyz.com:8090/confluence" route=2

        ProxySet lbmethod=byrequests

        ProxySet stickysession=ROUTEID

    </Proxy>

    # Main Confluence lb rules

    ProxyPass / balancer://confluence-cluster/

#    ProxyPass /balancer-manager !

#    ProxyPassReverse / balancer://confluence-cluster/

    # Main Confluence Reverse Proxy Rules

#    ProxyPass /confluence http://localhost:8090/confluence

#    ProxyPassReverse /confluence http://localhost:8090/confluence

</VirtualHost>

In this setting

    <Proxy "balancer://confluence-cluster/">
        BalancerMember "http://abc.xyz.com:8090/confluence" route=1
        BalancerMember "http://pqr.xyz.com:8090/confluence" route=2
        ProxySet lbmethod=byrequests
        ProxySet stickysession=ROUTEID
    </Proxy>

    # Main Confluence lb rules

    ProxyPass / balancer://confluence-cluster/

Replace this with,

    <Proxy "balancer://confluence-cluster">
        BalancerMember "http://abc.xyz.com:8090/confluence" route=1
        BalancerMember "http://pqr.xyz.com:8090/confluence" route=2
        ProxySet lbmethod=byrequests
        ProxySet stickysession=ROUTEID
    </Proxy>

    # Main Confluence lb rules
    ProxyPass "/" "balancer://confluence-cluster/"
    ProxyPassReverse "/" "balancer://confluence-cluster/"

Mainly I have remove extra '/' from '<proxy' tag and added 'ProxyPassReverse' to settings.

Nop....same old behavior.

I also see a lot of below errors in the browser:

Refused to apply style from 'http://abc.xyz.com/confluence/s/1ad5cc50d1baa5846ea9999535f9c82d-CDN/9ownmc/8401/8e8f74c7e2fea2df662fe8d0f5d79ff6ab016336/f08b142073ed75abbdbf91b355e73766/_/download/contextbatch/css/_super/batch.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Let me check for config on my site, and I will also ask Confluence team for look for this MIME type issue.

Can you detail about version of Confluence etc.
