  • What happens if you visit localhost:8986/solr in a browser?

  • I'm guessing the cert isn't trusted. If you look at the Solr script from the link you provided (the PowerShell script), you can see how it manipulates Solr. The script edits a few files to set up the SSL connection. Go through and verify that the steps completed correctly.

You need to update the SolrUrl in both JSON files for Sitecore and Solr. Please note that the Solr url with https should be something like https://{solrHost}:{solrPortNumber} based on the URL you followed to configure https for Solr.

Please update the files and try once more.


You need to verify your TLS connection. It is blocked while executing the script. Add this line to your script:

[Net.ServicePointManager]::SecurityProtocol = ([Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12)
  • can you please specify where do i need to add this line in the script, whether this line needs to be added in the solr script or while installing sitecore instance script. Please check this blog "flux-digital.com/blog/…" once and please suggest where have to add this line .
