Background

IMPORT from Azure Blob Storage didn’t work for a particular HTTPS proxy setup and failed with error

SQL Error [42636]: ETL-5500: An error occurred with Azure Blob storage: Fail to get a new connection for: https://<something>.blob.core.windows.net. SSL peer certificate or SSH remote key was not OK

Improvement

One can skip certificate verification for HTTPS proxy using DB parameter etlAzureCheckCerts. By default etlAzureCheckCerts is 1 (true) and we will have certificate verification for HTTPS proxy. To avoid blockage for customer to use HTTPS proxies, customer can set etlAzureCheckCerts to 0 (false) and everything will work fine.
