SSL on origin and cloudflare ERROR 502

I’m running a server that works when SSL is not enabled on origin server

When Universal SSL is off but Origin has SSL my browser gets error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

If server has Cloudflare Origin Cert and SSL set to Full (Strict) I get a cloudflare page 502 bad gateway.

My browser is brave. Does the same one Edge

I’ve tried Let’s Encrypt

I’m also using Zero Trust Tunnels

Can you get logs from cloudflared service where your tunnel is running? See Tunnel logs · Cloudflare Zero Trust docs

I can’t find the uuid how do i get that

You view on the dashboard or run cloudflared tunnel list to find a list of tunnels and their IDs.
