Crowd 3.7.0 console won't load - returns 504

[mw_sysop]

After upgrading Crowd from 3.4.4 to 3.7.0 the console won't load.

https://crowd.example.com shows the "Set up Crowd" button, clicking on that button redirects to https://crowd.example.com/crowd/console but this page won't load and returns 504 after 1 minute (browser timeout)

This happened with Crowd 3.5.0 as well. When going back to 3.4.4 everything works fine again.

Any help would be greatly appreciated

Hi @mw_sysop ,

I am sorry that you are facing issues while setting up the latest Crowd.

Can you please check Crowd logs and paste any errors that you see in the logs?

Also, how did you upgrade Crowd from 3.4.4 ? Can you please share the process

Cheers!

Hi @Gaurav ,

The only errors I see in the log are about application links:

Caesium-2-1 WARN [atlassian.applinks.core.DefaultApplinkStatusService] Unrecognized error while attempting to retrieve status of Application Link 'c82cfacc-1197-3d0c-9b9f-ad6445787b73'

When the server is started and the main page with the "Set up Crowd" button is shown the log stays empty.

To perform the upgrade I used the tar.gz archive:

1) stop Crowd
2) download archive
3) extract
4) change ownership of the files
5) add MySQL connector to {INSTALL_DIR}/apache-tomcat/lib
6) change reverse proxy settings in {INSTALL_DIR}/apache-tomcat/conf/server.xml
7) set correct path to Crowd home directory in {INSTALL_DIR}/crowd-webapp/WEB-INF/classes/crowd-init.properties
8) remove symlink to old version
9) create symlink to new version
10) start crowd 

I have used the above process for all upgrades over the last few years
