Hi @welaunch

your server sends a http status 401, so Letsencrypt can't check the validation file.

Same as your other domain ( dev.welaunch.io - Make your website better - DNS, redirects, mixed content, certificates ):

I see redirects (that's ok),

but in the end - a blocking 401. So check your folder permissions, the last url should send a http status 404 - Not Found.

Instead of sending everything to HTTPS only to have to deal with allowing unauthenticated access there.
You could NOT forward the /.well-known/acme-challenge/ requests; and handle then in HTTP.

In any case you will have to make some sort of exception for the authentication path.
It makes the best sense to me to do that “outside” the authenticated/secure system.
