+# Troubleshooting
+In rare cases, WebRTC may not work. The most common reasons are:
+* Tricky IPv6 configuration on the network. IPv6 support for WebRTC in Pi-KVM is still in its infancy, so if your network has IPv4, it will be easiest to completely disable IPv6 for Pi-KVM. To do this, switch the file system to write mode using `rw` command, add option `ipv6.disable=1` to `/boot/cmdline.txt` and perform `reboot`. Also see [here](https://wiki.archlinux.org/title/IPv6#Disable_IPv6).
+* A paranoid firewall when you try to connect to the Pi-KVM by forwarding port 443 to the Internet from the internal network. WebRTC is not enough of this, it uses UDP on ports 10000-20000 for a P2P connection. Make sure that the Firewall does not block them.
+* If nothing helps, open the browser's JS console and look at the log, and contact our community via [Discord](https://discord.gg/bpmXfz5). Developers and/or experienced users will definitely help you.
