When I have multiple subscriptions only one subscription is initiated when establishing an mqtt connection. #13162

Is there an existing issue for this?

Describe the Issue

When I have multiple subscriptions, and all of them are active, only one subscription succeeds when I click the connect button. Although the other subscriptions appear to be successful, they are not actually subscribed, which can mislead users into thinking the subscriptions were successful. I believe this is an issue.

Steps To Reproduce

  1. Disconnect the MQTT connection.
  2. Create multiple subscriptions under the "topics" section. image
  3. Click the connect button, and after successfully connecting, all subscriptions are shown as subscribed. image
  4. However, only the first subscription succeeds, and the other subscriptions fail to establish.

Hey @XiaoMing0000! I cannot recreate this on our end following the mentioned steps. I can successfully subscribe and receive events on all the listed topics.

Can you confirm if this is not a server issue? If not, can you share a scaled-down version of your server so we can investigate further?
