Confluence with Synchrony, behind IIS reverse proxy

[nbic]

Background information:

• Windows Server 2012R2
• IIS 8.5
• Confluence 6.7.2-x64
• DNS entry set, pointing to server.mydomain.com

Installed and configured Confluence with pre packed Tomcat, and everything worked fine running on http://myserver:8090/. All good, but I do not want my users to access this through http, nor through port 8090 - since IIS is already serving 80/443, reverse proxy in IIS seems like the obvious solution.

Sadly, this should be a task faced with some hurdles.

• I have edited the tomcat server.xml-file found in the following folder: atlassian/confluence/conf
  <Connector port="8090" connectionTimeout="20000"
                  maxThreads="48" minSpareThreads="10"
                  enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
                  protocol="org.apache.coyote.http11.Http11NioProtocol" proxyName="url.mydomain.com" proxyport="443" scheme="https" secure="true" />
  
  //Is there a way to check from the command line that the running instance is actually loading this configuration? (I have a hunch that it's not.)
  • Confluence is running as a windows-service, is there a way to configure the service itself, i.e with, tomcat8w to set proxyport/scheme and proxyname - to ensure that the correct configuration is loaded?
• I have set up a web.config file for my website in IIS with the following configuration:
  <?xml version="1.0" encoding="UTF-8"?>
  <configuration>
      <system.webServer>
          <rewrite>
              <rules>
                  <clear />
          <rule name="Synchrony HTTP" stopProcessing="true">
              <match url="synchrony/(.*)" />
              <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
              <action type="Rewrite" url="http://localhost:8091/synchrony/{R:1}" />
          </rule>
          <rule name="Synchrony Web Sockets Reverse Proxy" stopProcessing="true">
              <match url="ws://(.*)" />
              <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
              <action type="Rewrite" url="ws://localhost:8091/{R:1}" />
          </rule>
          <rule name="Confluence Reverse Proxy" stopProcessing="true">
              <match url="(.*)" />
              <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
              <action type="Rewrite" url="http://localhost:8090/{R:1}" />
          </rule>    
                                                  
              </rules>
          </rewrite>
          <security>
              <requestFiltering allowDoubleEscaping="true" />
          </security>
      </system.webServer>
  </configuration>
• IIS is set with bindings only on 443 for the website serving my URL

I have the following issues within my confluence solution:

• I get an error suggesting my Tomcat configuration is incorrect.
  • The Tomcat server.xml has an incorrect configuration:

    scheme should be 'https'
    proxyName should be 'url.mydomain.com'
    proxyPort should be '443'

• Editing posts does not work as expected, with the following symptoms:
  • The "statusbar" on the bottom says "Connecting...".
  • The following error appears after a while:

    • The editor didn't load this time

      The connection timed out. If it happens again, speak to your Confluence admin. You may be using a proxy server that prevents WebSocket connections.

I feel I have double and triple checked everything, but cannot get this to work, so any suggestions would be highly appreciated.

This has been resolved. It was shamefully simple.

<Connector port="8090" connectionTimeout="20000"
                maxThreads="48" minSpareThreads="10"
                enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
                protocol="org.apache.coyote.http11.Http11NioProtocol" proxyName="url.mydomain.com" proxyport="443" scheme="https" secure="true" />

This was my connector directive in Tomcat. Well, the "proxyport" needs to be "proxyPort", since it's case sensitive. Seems like the whole directive was ignored, due to that typo.

Do you have the IIS WebSocket feature added to your machine? 

Add role -> Web Service (IIS) -> Application Development -> WebSocket Protocol

I have the setup you are trying working within Azure. WS2016 based proxy (terminating SSL) and Confluence running as a service on WS2016 server.

Thanks for your suggestion, but the answer was simpler than this.
