your log has cef errors. try launching steam client with -no-cef-sandbox
SteamLink at least connects for me (Pico4, Arch Linux/CachyOS repos) if I switch to the SteamVR beta.
i am a dumbo, for some reason i wasnt on the beta version of steamvr lol
I encountered the same problem on:
- Arch
- Hyprland (Wayland)
- Nvidia driver 590
- Steam from official repo
- Steam VR Beta branch
- Proton GE 27
On the first launch Steam Link connects without issues and Steam VR loads Home environment. However, upon launching any game, it disconnects with error 450 "Host not responding".
For me it was setting QT_QPA_PLATFORM=xcb %command% in SteamVR launch options, then setting SteamVR as the default OpenXR runtime and possibly disabling Steam VR Home.
For me it was just disabling SteamVR home.
First I tried both - to add QT_QPA_PLATFORM=xcb %command% and disable SteamVR home (SteamVR -> Properties -> Workshop - disable all collections), then I restarted the PC and SteamLink app in Quest 3 and it starts to work.
Added 1 hr later:
Now it doesn't work anymore with the same 450 error in SteamLink and I didn't do anything to it, I'm genuinely confused.
After restart it again shows Home for the first time then fails with
Missing interface adapter for STEAMTV_INTERFACE_V001
I was having the same issue as well, but I managed to fix it by whitelisting the following ports on ufw:
sudo ufw allow 10400:10401/udp
sudo ufw reload
also depending on how you have your computer setup you may also run into "streaming vr is only supported on the local network" after doing this, for anyone coming across this issue you can do the following:
sudo ufw allow from 192.168.0.0/24 to any port 27031 proto udp
sudo ufw allow from 192.168.0.0/24 to any port 27036 proto udp
sudo ufw allow from 192.168.0.0/24 to any port 27036 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 27037 proto tcp
sudo ufw reload
note: you can set it to 192.168.1.0 (if your network uses 1)
alternatively if you want to allow any device
sudo ufw allow 27031:27031/udp
sudo ufw allow 27036:27036/udp
sudo ufw allow 27036:27037/tcp
sudo ufw reload
