Dear team,

Thanks for your feedback!

We tested this bug and found that it is impossible to request data in the Wi-Fi environment of IPV6, but it is possible in the Wi-Fi environment of IPV4.

In China, we usually use the IPV4 network environment, and our server also sends data through the IPV4 network. In order to upgrade the server through auditing, it takes a lot of time and money. Our application is only sold in China, could you test with the IPV4 network environment? I believe that these bugs will not appear, thx!

Best Wishes.
