Categories are not listed :: snipe behind apache2 Proxy

[DonKingMat]

Fresh installation without any errors on Ubuntu 24.04.1 LTS (Noble Numbat)
Some example licenses added
categoriy can be set but can not be choosed from previously created. The dotted circle does not move and no previous categories will be shown.

There must be something more to configure within the apache2 config? I was following your guide first which makes it in general accessible behind a proxy but not that specific drop-down function.

apache2 config (secrets are hided by Q):

<VirtualHost Q.Q.Q.Q:443>
    # ProxyPreserveHost On
    RewriteEngine On
    SSLEngine on
    SSLProxyEngine On
    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off
    SSLProxyCheckPeerExpire off
    ServerName snipe.Q.Q:443
    RequestHeader set X-Forwarded-Proto "https"
    ProxyPass / http://Q.Q.Q/
    ProxyPassReverse / http://Q.Q.Q/
    SSLCertificateFile /etc/pki/QQQ/Q.Q.crt
    SSLCertificateKeyFile /etc/pki/QQQ/Q.Q.key
    SSLCertificateChainFile /etc/pki/QQQ/Q.Q.intermediate.crt
</VirtualHost>

snipe-it .env config snippet pointing to my reverse-proxy:

root@QQQ:/var/www/html/snipeit# grep PROX .env
APP_TRUSTED_PROXIES=Q.Q.Q.Q

Can you show me the browser console output when you try to use one of those dropdowns that fail?

I have same issue and upload to Discord too.

@leductho911 In your case, the browser is telling you what's wrong - mixed content warning. It's loading the GUI page over https, but the javascript is loading over http.

Can you show me what your APP_URL is set to in your .env is? I see public in the web GUI URL, which should not be true in most cases.
