Problem updating ACME TLS-SNI-01 to alternative validation method


#242

Thanks for this hint. However, it is hard to find the last successful validation there (lots of logged information).

I have found even better, that the renewal configuration files are in this folder:
/etc/letsencrypt/renewal
In my particular case I find this parameter there:
pref_challs = dns-01
I assume that this means we are NOT using the offending TLS-SNI-01 nethod, and that therefore no action is required.

I wish that the seriously sounding email notification had included information about how to perform this basic check.

This doesn’t seem to add up thou.
If you received an email, then you have used TLS-SNI-01 (recently).
