Question about posting to byte platform websocket

The web test and the Byte Development Tool test can be connected normally, but the real machine debugging and code scanning test (including changing the mobile phone to try) will report an error and break at the new websocker() step

There is no message for the corresponding monitoring including onerror. I don’t know how to locate the problem.

Is there no legal domain name configured in the background?

Configured. In the development tools, this is not checked

3453453453

I confirmed again that the domain name in the backend configuration is indeed configured with this address, but in the developer tools, whether I check or not to check, I can connect normally. In the real machine debugging mode, I can only connect normally if I check not to check. In the preview mode, I can’t connect normally… Is this still a problem with the domain name?

Can I connect to the real machine with debug mode turned on?
