Getting this error while connecting to desktop. This was working fine past week but getting this error from yesterday.

ERROR
Response 500 on handshake url http://localhost:9000/api/handshake : {"code":500,"message":"Error: Could not establish connection to data-api-proxy-csm","stack":"Error: Error: Could not establish connection to data-api-proxy-csm\n at C:\Program Files\Refinitiv\Refinitiv Workspace\1.26.831\resources\app.asar\node_modules\eikon-api-proxy-core\scripting-proxy-core\services\csm-application-key-validator.js:23:23\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"}

I am using the following code
import lseg.data as ld
ld.open_session()

to connect

This could be the problem in the backend service.
