We are continuously updating our service to ensure security is in line with organization recommendations and company requirements. As part of the Microsoft-wide “TLS 1.2 everywhere” initiative, Azure Data Explorer will stop accepting requests made using Transport Layer Security (TLS) 1.1 or older and will require TLS 1.2.
This will affect all Azure Data Explorer APIs, including Azure Resource Manager APIs (i.e. APIs used to create Azure Data Explorer clusters and databases).
This will affect all applications, clients, and code that use Azure Data Explorer APIs with older TLS versions.
To avoid any service interruptions, please ensure that requests issued to Azure Data Explorer use at least TLS 1.2.
For solving TLS 1.0 issues and more instructions please use the following links:
