Unable to complete execution of health check Collaborative Editing Mode due to an exception

[David Bonet Montes]

Hello all,

I have this error in our Confluence server (latest version).

All is working unless collaborative edition. In the logs, when I set the debug mode shows this log:

WARN [HealthCheckWatchdog:thread-3] [troubleshooting.healthcheck.concurrent.SupportHealthCheckTask] healthCheckError Unable to complete execution of health check Collaborative Editing Mode due to an exception

It confuses me because the base url is set. I'm in a subdomain (like confluence.mycompay.com) and my base url is correct. I edited this fragment of the server.xml.

        <Engine name="Standalone" defaultHost="localhost" debug="0">
            <Host name="localhost" debug="0" appBase="webapps" unpackWARs="true" autoDeploy="false" startStopThreads="4">
                <Context path="/" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true">
                    <!-- Logging configuration for Confluence is specified in confluence/WEB-INF/classes/log4j.properties -->
                    <Manager pathname=""/>
                    <Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
                </Context>
                <Context path="${confluence.context.path}/synchrony-proxy" docBase="../synchrony-proxy" debug="0"
                         reloadable="false" useHttpOnly="true">
                    <Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
                </Context>
            </Host>
        </Engine>

As you can see I set the  path to "/" instead of empty. But still the exception says that is null. In the global configuration I have the base url set correctly.

Do you have any idea of why is that failing?

Hi! Finally it came to be a Confluence cloud to server migration bug: https://jira.atlassian.com/browse/CONFSERVER-45919

Just edit and save the general configs and it solved the problem
