this one adds to Let's encrypt whitout Port 80 , since I came here because my ISP blocks port 80 and therefore I can’t renew my certificates. Changing the ISP is not an option.
So to change Let’s encrypt to use Port 443 I wanted to change the validation type to TLS-ALPN.
I just wonder how this could be done or whether it could be done at all (with or without the lets encrypt app).
I think I need to install mod_md on Apache (https://github.com/icing/mod_md), but I haven’t done yet and worry to just break everything. Has someone already switched the vallidation type on lets encrypt and can give me some advices?
