We want to inform you that WebSocket v2 has now been fully deprecated as of yesterday, 22 August 2025.

All customers should now migrate to WebSocket v3, which provides improved stability, scalability, and additional features. If you have not already done so, please update your systems accordingly to avoid disruption.

We thank you for your cooperation and support during this transition.

Hi @Pradeep_Jaiswar

I would like to request you to add new category while creating community post for bug reporting which will be monitored by dedicated team to fix reported bugs quickly. Currently when we report any bug it is taking days to just acknowledge that we are checking it and also ask UCC id mandatory while creating post or registering at community so that you don’t waste time asking UCC on every post.
