Various issues #15037
Description
Description
I'm trying to install coturn with docker, But when I put the command in it gives me an error "Cannot connect to docker API", and the resulting container that showed up in docker gives me and error saying "connect ENOENT . \pipe\dockerdesktopengine" and after trying to do anything a "Failed to fetch extensions" error will show up, and Trying to restart docker with the button returns the same "Failed to fetch extensions" error.
Reproduce
Run "docker run -d -p 8080:8080 -p 40000-40100:40000-40100/udp -e WEBRTC_NAT_1TO1_HOST=YOUR_LAN_IP mrcreativ3001/moonlight-web-stream:latest" with YOUR_LAN_IP replaced with your local IP for moonlight web
Run "docker run -d -p 3478:3478 -p 3478:3478/udp -p 5349:5349 -p 5349:5349/udp -p 49152-65535:49152-65535/udp coturn/coturn"
Expected behavior
It should properly add the coturn server as a container

Hi @jjasome11,
Thanks for reporting this. The coturn/moonlight commands aren't actually the issue here — the error shows Docker Desktop's engine isn't reachable at all (dockerDesktopLinuxEngine pipe not found), so any container would fail the same way right now.
A couple of things to try:
If a full quit + wsl --shutdown doesn't get the engine back, a reboot is the next thing worth trying before we dig further.
