Action required: Let's Encrypt certificate renewals


#1

Hi there

I’ve received an email stating that letsencrypt will only be supporting TLS-ALPN-01. I have a web currently on SSL with certbot. How do I do I check whether my certbot is using TLS-ALPN-01 and if not how do make it?

And if Certbot do not support TLS-ALPN-01, is there any other alternative to get this to work?

Thanks

Certbot doesn’t support TLS-ALPN validation.

Recent versions of Certbot use HTTP validation instead of TLS-SNI validation.

Certbot also supports DNS validation.

Unless you’re completely unable to use port 80, it should be easy to upgrade Certbot and automatically use HTTP validation.

If using TLS-ALPN validation is your only option, you would have to look into other ACME clients.


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:
