please guide

@Ushnota I am stuck because of the above issue. It has been more than 14 days and I haven’t received any reply. Can you please help me resolve this?

Hi @RAM_KRISHN_1864028

There could be a case in your implementation where multiple connections are being created without your awareness. For easier WebSocket implementation, you can refer to the streamer functionalities available in the different SDKs:

You should be able to connect up to 5 simultaneous connections to the Market Feeder v3. Could you please share your user ID so we can investigate further if not able to connect to 5 connections?

5

Sir same issue with me not allowing more than 1 few mins back i was using 3 more connection but suddenly its not happening

6

My userid is AB8793, I have used this version upstox-python/examples/websocket/market_data/v3 at master · upstox/upstox-python · GitHub , is the streamer functionalities different that the one I am using ?

7

@Ketan can you please look into and suggest?

8

@Ushnota could you please get it checked ? let me know if your team need more info

Hi
I checked for your user ID and found that your last connection was on 23rd September. No new authorized connection requests have been sent to the Market Feeder V3 since then.

On that day, our logs show five successful connections.

Please note that the streamer functions act as a wrapper over the WebSocket and provide additional functionalities such as:

  • Reconnection
  • Subscribe
  • Change mode
  • Unsubscribe

Could you please try again today and let us know if you face any issues?

Thanks!

Thanks, I rechecked my code after upgrading to streamer, here is the log.
