Failed to connect with Let's encrypt

Help
1

The server is running on Ubuntu and used certbot for automation. The error message received states: "failed to connect to let's encrypt server. Please check your network connection and firewall settings. There have been no recent changes to the network configuration or firewall rules. What could be the possible reason for this issue?

Welcome @Archie_Mj

Well, sometimes there are temporary comms problems that can cause that. Such as at your ISP or backbone networks. Or, even temporary issues in the Let's Encrypt server farms.

Does this problem repeat? If so, what does this show?

curl -I https://acme-v02.api.letsencrypt.org/directory

And, what version is your Ubuntu and what version does this say

sudo certbot --version

the outputs:

curl -I https://acme-v02.api.letsencrypt.org/derectory:

Content-Length: [Content-Length]

Cache-Control: public, max-age=0, no-cache
X-Frame-Options: DENY

sudo certbot --version:

Based on these results, what would be the next steps to diagnose and resolve this issue?
