ERROR [org.alfresco.solr.tracker.AbstractTracker] Model tracking failed

Hello,

I am facing this issue on alfresco platform, document search no longer works in ALFRESCO 5.0.2 community - search engine only works on user list not on all our documents anymore.... We didn't touch anything on the server.
and when I consult the solr logs in the solr.log file I see this error which repeats several times:

The error "java.net.ConnectException: Connection refused: connect" indicates that there is issue with communication between alfresco and solr.

Please review your setup and make sure both apps are able to ping each other.

Following properties plays role in this communication:

1- In alfresco-global.properties:

solr.host=localhost
solr.port=8983
solr.port.ssl=8443
solr.secureComms=none #Possible values are: none, https (newer versions such as acs7 and solr6 (ass 2.x) supports "secret" as well)

2- In solrcore.properties

alfresco.host=localhost
alfresco.port=8080
alfresco.port.ssl=8443

#Possible values are: none, https (newer versions such as acs7 and solr6 (ass 2.x) supports "secret" as well)
alfresco.secureComms=none

Make sure your set up is approriate. If you are using ssl, make sure cerficates are configured properly.
