Frigate Proxy ingress Dashboard doesnt load

Hello,
My Frigate proxy panel doesnt work inside home assistant, ingress is loading for a minute and gets 504 error(localy) error 502(clodflared), how can i fix it?

-Home assistant server(proxmox) is cloudflared
-Frigate is installed on my vps oustside home network(tailscaled)
-To connect frigate with my reolink nvr I use tailscale, everything is tailscaled including my homeassistant server and it works well
-I installed frigate proxy, connected it to my homeassistant and i can get blank(without snapshot/video) push notifications(made automation for it)
-Installed frigate hacs integration, but cant connect to it, using tailscale ip adress with:5000

In frigate proxy i can see only:
