ERROR [org.alfresco.solr.tracker.AbstractTracker] Model tracking failed javax.net.ssl.SSLHandshakeEx

redouane — Wed, 19 May 2021 16:23:05 GMT

Hello,

I have been facing this issue on the development environment for two weeks,

Can anyone tell me what could have been done to correct this error.

After this error, the search for documents no longer works in ALFRESCO community 5.0.2 - the search engine only works on the list of users and no longer on all our documents .... We have not touched anything on the server .

alfresco version installed: Alfresco Community v5.2.0
solr version: solr4

Please find previous solr and alfresco logs below when my alfresco is started.

It seems like certificate issue. Try creating/adding new certificates to the keystore.

Check this thread as well: https://hub.alfresco.com/t5/alfresco-content-services-forum/solr-tracker-sslhandshakeexception/td-p/222808

If you feel SSL based authentication is not required, you could choose to disable it and use non ssl based setup depending on your use case.
