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](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: abulo.dev
I ran this command: certbot certonly --standalone -d abulo.dev
It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator standalone, Installer None

Hi,
Could you please run the below test and see if you can access Let’s Encrypt API server?
(Please post the full response content here)
`curl -i -v https://acme-v02.api.letsencrypt.org/`
`dig acme-v02.api.letsencrypt.org`
`ping acme-v02.api.letsencrypt.org`
Thank you

@stevenzhu, when I ran the above on the server’s terminal, all looks good, I can connect and receive back bytes with the ping. I only get the connection error when I attempt to get the SSL certificate.

Hi,
Can you try to see if the below solution is also working for you?

Note that hardcoding IP addresses like that will no longer work – the API uses different infrastructure now, which uses anycast routing and IPs that do not change frequently.
It does potentially sound like an MTU issue, though.
Can you post `/var/log/letsencrypt/letsencrypt.log` from when the issue happened and before it?
