Just starting to try out this new PicoKVM. After swapping cables and computers, I am always faced with this "Connection Issue Detected" message when accessing the web interface of the module. Suggestions? Screenshot attached.

Hello, this issue usually occurs due to a disconnected network connection. Currently, we recommend that you log in to the terminal via SSH to test if the connection is stable (you can use the iperf3 command).

Thank you. I'm on holiday and won't be home for a day or so, but will try this.

I didn't realize the device was listening on SSH. The network connection does seem stable. If I ping -t the device remotely on the same LAN for example, there is no jitter or dropped echo requests. My network is locked down a bit. I prevent public DNZ queries both UDP 53 and DoH/DOT. Only my internal DNS server handed out via DHCP is usable. Not sure if this would have any impact?

Regards,
Adam Tyler

我有相同的問題,除了剛開機可以使用以外99%時間都無法使用😐

我時常關注wiki上的韌體更新,每當有新的韌體我都會更新,但始終無法解決問題。

在LAN上可以正常使用SSH連線,網路一切都相當正常

噢! 對了 在iPad上使用滑鼠的位置似乎是錯誤的,這或許是個bug。

非常期望這個裝置可以正常使用,謝謝工程師😀

方便说明一下您的网络拓扑结构吗?比如有没有使用旁路由,各个设备是怎么连接路由之类的,目前视频流的传输通过webrtc在收集 ICE Candidate的时候会枚举本地的IP,正常IP如果是DHCP 分配的局域网内进行P2P是没有问题的,但是目前来看ssh连接上了但是P2P没有建立成功,局域网内能ssh但是P2P失败的原因目前我们还没能复现出来。
对于手机平板设备的界面优化我们正在进行,后续识别设备所处的平台使用不同的布局,解决键鼠错位问题

首先非常感謝您的說明幫助了我找到問題,問題確實在於WebRTC,這讓我清楚定位到了問題所在。

由於我的網路拓樸經過NAT及反向代理,我目前嘗試使用Cloudflare Tunnels已經解決問題,非常感謝您。

再次感謝您的協助,最好的問候。

註: 關於iPad的問題,是指使用iPad的Type-C作為影像輸出連接至PicoKVM時會發生滑鼠位置上的錯誤,而不是手機平板瀏覽PicoKVM網頁佈局上的問題。

I have this issue with chrome browser - stuck on "Establishing secure connection"... but there is no problem in Microsoft Edge browser.
