Question / Problem:
When using Azure blob storage for storing your processed document and you have entered the correct connection string you might get the error message (pop up) shown below
Error after entering correct connection string
Answer / Solution:
This is due to the version of TLS been used and needs to be modified as per the steps provided below
Enter How to here:
- Run a fiddler trace. The result of the trace would show something like "The TLS version of the connection is not permitted on this storage account "
- If you are using TLS 1.0, TLS 1.1 and TLS 1.2 enabled on your environments.
When TLS is used, it will start with the lowest - hence you get the above error message when you create a storage account with the Azure portal, the minimum TLS version is set to 1.2 by default thus it rejects the TLS 1.0 connection attempt,
- You have two options to modify the TLS
Option 1 - Lower the minimum TLS required in the Azure Storage Account
To configure the minimum TLS version for an existing storage account with the Azure portal, follow these steps:
a. Navigate to your storage account in the Azure portal.
b. Select the Configuration setting.
c. Under Minimum TLS version, use the drop-down to select the minimum version of TLS required to access data in this storage account, as shown in the following image.
Option 2 - Follow the steps in this link to add 2 registry keys
The TLS version used by Azure Feature Pack follows system .NET Framework settings. To use TLS 1.2, add a REG_DWORD value named SchUseStrongCrypto with data 1 under the following two registry keys. (Make sure to backup this registry prior to making changes)
