Hello @CarloJason.Arcega

I have checked the case 1332037x, I cannot find any information about the Python version, WebSocket version: 1.6.1 and refinitiv.data Module version: 1.6.0 on the case. Where did you get this information?

By the way, does the client connects to the RTO (I saw you mentioned the Machine-ID on the case), or the deployed ADS with the SSL Accelerator? I did a quick tested with the Python 3.7.16/WebSocket-Client 1.8.0 using both RTO - market_price_rdpgw_authentication.py (connect to WSS ADS on the Cloud) and RTDS - market_price.py (connect to local ADS). They work fine and can connect to ADS successfully.

Note: I do not have the deployed ADS with SSL Accelerator in my environment.

Please be informed that we, Developer Relations can help with the LSEG APIs general usage questions only. For this kind of question, we can help to verify if the client's source code uses a valid Real-Time WebSocket API specification. If the client already uses a valid code, but the problem is still persisting. I strongly suggest you contact the ADS support team as the WebSocket API is the server-side API.
