Hello Experts,

I am using BC online Sandbox and facing an error while downloading symbol in Visual Studio Code. See the below error detail and attached screen shot for the same.

"Error: The SSL connection could not be established, see inner exception.

Authentication failed, see inner exception.

The client and server cannot communicate, because they do not possess a common algorithm."

Thanks in advance for your kind support to resolve the issue.

Regards,

Ranjith

Hi, I've only seen this problem before in the On-Pre version, as discussed in the link below.

I just tested it in my environment and it looks ok, so if it happens in your SaaS environment, it is recommended to contact Microsoft.

Hope other experts can give you better advice.

Thanks.
