Why it takes 2+ minutes to get certificate?

Hello Everyone,

I use certbot auto to request certificates. It used to only take 5 seconds to get certificate but now it takes over 2 minutes to get one. My servers have decent uplink, no load and proper DNS configured on them.

Here is my certbot log for your reference: https://pastebin.mozilla.org/8926015

I use this command to request a cert: certbot-auto certonly -a webroot --webroot-path=/etc/letsencrypt/live --keep-until-expiring --non-interactive -d DOMAIN_NAME

What would be the issue?
Please advise

Any chance your server has a broken IPv6 configuration? If so, you might be running into this issue. Fixing your IPv6 configuration or disabling it altogether should solve this.
