MQTTX web fails to connect when disabling SSL security with wss, but the desktop version of MQTTX works.

[ZKUTF-8]

What I did:

I tried connecting using the web version of MQTTX with wss while ignoring SSL security

but it failed to connect. However, it works with the desktop version.

Environment:

OS: Windows 11
MQTTX version: e.g. v1.9.5
EMQX: Running on Docker 5.1.6

Detailed Information:

I need to use wss under HTTPS. Following the official guide, I used mqtt.js. Since certificates are required, I set the rejectUnauthorized: false to ignore verification. The result was a connection failure. So, I tested using MQTTX's web and found it also failed. However, it worked with the desktop version of MQTTX. I'm very puzzled, and this issue has troubled me for a long time. Thank you very much.

After installing EMQX, I didn't make any configurations. Did I do something wrong? Or can't SSL verification be ignored in a web environment? However, mqtt.js said it's possible. Thank you very much.

Hello @ZKUTF-8,

I apologize for the delayed response. After conducting some tests, I've found that using MQTT.js in a Node.js environment works fine, but not in a browser setting. This could be attributed to the differences between the two environments. It's worth noting that MQTTX desktop operates in a Node.js context.

I've tried configuring the WSS for emqx without success. You should correctly set up the SSL/TLS certificates for emqx to establish a successful WSS connection. For further assistance, I'd recommend posting on the EMQX forum to inquire about the right way to configure WSS.

I deeply regret the inconvenience this has caused, and I appreciate your understanding.
