Hi there,
Is the problem resolved? In my device it seems like that the app was trying to connect to an incorrect port, but I don't know how to correct it. I couldn't find a button like "Set connection port" in the app.

The error message is as follows:

TCP connection to 127.0.0.1:46497 failed

Caused by:
    Connection refused (os error 111)

Here is the screenshot of my Wireless Debug settings, which shows that the connection port is 34133

For me, I am temporarily using logcat | grep https to manually find out the link, but I don't consider it as a long term plan. The project is good.

@shc0743 This can be caused by the mDNS auto discovery started by your system didn't close correctly, have you tried restarting your phone? This can usually force the system service to restart.

I tried to restart my device, but after that, the problem changed to "证书失效，请重新配对". I tried to pair again, but it still didn't work.

“Connection refused”那个问题的原因找到了，如果设备开机后首次打开无线调试的开关然后连接，就没有问题；如果开机后打开了无线调试，关闭后又重新打开（可能是用户手动关闭，也可能是由于wifi网络切换触发的系统自动关闭），此时会自动更新无线调试的端口号，但Ascent不知为何仍然会尝试连接首次打开无线调试时的端口号（且无法手动修正），自然就连不上

另外还有一个“证书失效”，重启之后可能会触发，也可能可以正常连接，具体原因不明

Ascent每次会扫描本地的mDNS服务来确定连接端口，这代表你系统的mDNS服务没能正常更新，我后续会加一个设置项关闭自动检测端口的功能，这应该可以修复该问题
