I have been trying to renew my certificate for zespri.dedyn.io for the last two days, without success. I tried, like the many times before, to run
sudo certbot --apache renew, which would fail with the same error as
sudo certbot -a webroot -i apache -w /var/www/html:
Failed authorization procedure. zespri.dedyn.io (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://zespri.dedyn.io/.well-known/acme-challenge/OGqPh904NK_KUJFQ3-QRRlGsv9J9WLqy523JwIa2qsk: Error getting validation data. Skipping.
I do realize that it has to do with the deprecation of TLS-SNI-01, but I am lost looking for a workaround. I am on Ubuntu with Apache 2.4.18 and OpenSSL 1.0.2g.
Thank you for consideration!
