Cloudflare Warp Beta (now Argo Tunnel)

I’m trying to setup Wordpress behind warp and I keep getting 502 errors when trying to access the admin area of wordpress. Any suggestions? I have seen people who disable apps, caching, etc for the /wp-admin/* area but that doesn’t seem to help. Need to come up with a good recipe for setting up warp with wordpress.

I notice that I am getting keep alive errors:

error=“Get https://blog.private/wp-login.php: http2: invalid Connection request header: [“Keep-Alive”]”
