Wildcard domain ssl error

[FifthWit]

Hi I setup dokploy and gave it a wildcard cert, and turned off proxying from cloudflare so I can get the certs, and whenever I try to visit the application i deployed and set the domain to a subdomain of my wildcard, and firefox gives me an error like this:

Secure Connection Failed

An error occurred during a connection to the url of the site. Cannot communicate securely with peer: no common encryption algorithm(s).

I also redeployed after I set the domain since I saw that as a step on a github issue. But still doesnt work

oh after some time now it kinda works, but its a self signed cert so i cant actually use it for prod

I got it from Let's Encrypt, and I made sure to disable proxying so let's encrypt would be able to get the cert

you cant get wildcard certs using the standard http challenge with lets encrypt, you can only get a wildcard if you use DNS challenge, so its ok to proxy here, but you need to add your cf api key to traefik and set the DNS challenge

How do I do that?

so I watched the video here https://docs.dokploy.com/docs/core/videos and tried doing it with proxying and allat. So I removed the wildcard and defined the exact dns record, and kept proxying on. Then in dokploy I added the domain, forced https, and put the cert provider as Let's Encrypt, the domain says Behind Cloudflare in the webui, but when I visit it I still get Error code: SSL_ERROR_NO_CYPHER_OVERLAP

ah I fixed it. The issue is because I used a domain like one.two.three.com and Cloudflare just doesn't like domains with two sub domains I guess
