SSL_ERROR with .dev Domain

Hi there,

I am new to Cloudflare Zero Trust, so it may be an error on my side.

Here is the goal I want to archive.
Connect via to my homeserver which runs nginx Proxy Managers Proxy hosts (Services which run in my local network)

I did the following steps:

  1. Bought a new domain on Porkbun
  2. Added and activated to Cloudflare
  3. In Cloudflare Zero Trust I added a new tunnel (which is Healthy) with the following configuration
    Public Hostname

When I then open I am greeted with ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

When buying the domain from Porkbun I was informed that .dev require SSL. Thus Porkbun automatically obtained a LetsEncrypt certificate for me. In the Tunnel setup I removed all DNS entries from the Domain to remove all ties to Porkbun. I assume that the SSL (HSTS) issue should be solved by Nginx Proxy Manager, right?

Turned out it fixed itself!
