Why do I continue to get a Base URL warning?

1. it's scheme not schema

 <Connector port="8090"
  connectionTimeout="20000"
  redirectPort="8443"
  maxThreads="48"
  minSpareThreads="10"
  enableLookups="false"
  acceptCount="10"
  debug="0"
  URIEncoding="UTF-8"
  protocol="org.apache.coyote.http11.Http11NioProtocol"
  maxHttpHeaderSize="8192"
  useBodyEncodingForURI="true"
  scheme="https"
  proxyName="wiki.28beatty.com"
  proxyPort="443"
/>

/etc/httpd/conf.d/confluence.conf

1. notice that *.443 is abstracted out into two separate VirtualHost

2. notice that there is a *:8443 VirtualHost

3. notice the trailing / on the Redirect lines

Because your base url is not set to what you've set up as the proxy.

whoisearth

Please explain where in my config files that is not the case.

My base url within confluence is https://wiki.domain.com

Davin Studer

Your proxy is set as wiki.domain.dom. It should match your base url wiki.28beatty.com. One of them should change. Are you using a reverse proxy? If not then this part can be removed altogether ...

proxyName="wiki.domain.com" proxyPort="443"

whoisearth

apologies and updated for sake of other people I've changed all references to wiki.domain.com. rest assured all values are consistent on my end.

Per my conf.d file yes I'm using a reverse proxy.

Hi,

Just for the following readers... Working for Ubuntu Server (also general Linux with apache / reverse proxy )

In case your Bitbucket config (https) is working like you would expect BUT you face problems with the relation / connection from JIRA to Bitbucket and / or it throws base URL warnings ... you can do a simple thing to solve this time consuming stuff... Make sure that your virtual host (apache2) config is also redirecting from incoming port 80 to the right place... So i saw the comment of Robin (Thx for that) in top and "just" extended my config with the <VirtualHost *:80> ... <VirtualHost> Block. After that restart apache and Atlassian relations are working well without any disturbing base URL warning...

My Virtual Host Config

<VirtualHost *:80>

        Servername YOUR.PROJECT.COM

        Redirect permanent / https://YOUR.PROJECT.COM/

</VirtualHost>

 
<VirtualHost *:443>

  ServerName YOUR.PROJECT.COM

  ProxyPreserveHost on

  ProxyPass / http://localhost:7990/

  
RewriteEngine On

  RewriteCond %{SERVER_PORT} 80

  RewriteRule ^(.*)$ https://YOUR.PROJECT.COM/$1 [R,L]

  
SSLEngine on

  SSLCertificateFile /etc/apache2/ssl/YOURCERT.crt

  SSLCertificateKeyFile /etc/apache2/ssl/YOURCERT.io.key

  SSLCertificateChainFile /etc/apache2/ssl/intermediate.crt
