您好，感谢反馈，请问电脑和手机的Reqable版本分别是多少？

您好，感谢反馈，请问电脑和手机的Reqable版本分别是多少？

移动端是3.2.19；PC端为3.2.20

我这边也是会经常这样子，手机上一点连接闪了一下不知道什么字，然后秒变“设备已离线”，在电脑上能发现手机，点击添加设备，手机上就显示“连接失败，请检查您的设备网络状态后重试！”

重启电脑又能连上，按理说局域网内这么稳定的网络不应该这样

[liesauer]

这是从电脑点连接时的log，我不确定和wsl或者hyper-v有没有关系，但是以前（其他场景下，非reqable）也出现过这种类似的莫名其妙的端口问题，也就是端口被保留了。
