Problem

Confluence 6.1 to 6.5 displays the following message to administrators:

Can't check your base URL

There may be a problem with your proxy configuration.

Diagnosis

This message appears when Confluence attempts to check that the URL you are using to access Confluence is the same as Confluence's base URL, but cannot complete the check because of a problem with your proxy configuration

Cause

This message appears when Confluence attempts to check that the URL you are using to access Confluence is the same as Confluence's base URL, but cannot complete the check because of a problem with your proxy configuration. This is usually because:

  • proxyName and proxyPort are present in your <install-directory>/conf/server.xml file but you are not using a reverse proxy.
  • you are using a reverse proxy, but the values for proxyName and proxyPort  are incorrect in your <install-directory>/conf/server.xml file. 

Resolution

If you are not using a reverse proxy, make sure the proxyName and proxyPort attributes are not included.  Your connector should look similar to the example below if you are not using a reverse proxy:

<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" />

If you are using a reverse proxy, make sure the the proxyName and proxyPort attributes have correct values for your reverse proxy.  Your connector should look similar to the example below:

<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" 
     proxyName="www.example.com" proxyPort="80" scheme="http"/>

If you still see this error after checking your server.xml, check your proxy configuration is also correct. The following pages provide example configurations.
