I have Sitecore 8.2 update 5 in Azure PaaS using Azure Search. When I am trying to open the content editor, it is throwing exception Index has not been initialized with stack trace info mentioning cloud search provider.

I tried the rebuilding index which completed without adding any item to any index. Can anyone suggest what are the places I need to check?

You need to upgrade to TLS 1.2

For .Net Framework version 3.5 – 4.5.2 (Sitecore 8.2) explicit setting of TLS version is required.

Microsoft Azure is upgrading platform TLS libraries and support for TLS 1.2 is becoming the standard default. Sitecore customers running a Sitecore version prior to 9.0 may experience communication errors between Azure services, notably Azure Search. This can prevent Sitecore from completing routine query and index operations with Azure Search and cause a variety of complications.

On February 26th, Microsoft started rollout of Azure Search with enforce TLS 1.2 in use. Rollout started from US regions. Cloud Ops team is monitoring situation, however, recommended solution for customers is to apply the workaround described in KB article referred above.

  • Thanks a lot Mark. This saved our day :) .
