Vietnam and Akamai, name a more iconic duo.

What happens if you force IPv4?

curl -4 -Iv https://acme-v01.api.letsencrypt.org/directory

If that doesn’t work, what happens if you put this in /etc/hosts and try again:

104.97.250.189 acme-v01.api.letsencrypt.org

Yeah Great, i add 104.97.250.189 acme-v01.api.letsencrypt.org in /etc/hosts, the problems has fixed
Thanks you very much

Unfortunately that is not a long term solution, as the IP address will eventually change and stop working.

To confirm, IPv4-forcing curl request did not succeed (without the /etc/hosts workaround)? It is important to understand whether the problem is IPv6 related or a recurrence of previous Akamai Vietnam issues.

@nguyenhoang999
Could you temporarily comment out the changes to your /etc/hosts file and run the following commands? I’d like to pass this information along to the CDN.

mtr --no-dns -c100 --report https://acme-v01.api.letsencrypt.org
curl -4 -v -H 'Expect:' https://acme-v01.api.letsencrypt.org/directory -H "Pragma: akamai-x-cache-on, akamai-x-get-cache-key, akamai-x-get-true-cache-key, akamai-x-get-request-id"
curl -4 -v -X POST -H 'Expect:' https://acme-v01.api.letsencrypt.org/directory -H "Pragma: akamai-x-cache-on, akamai-x-get-cache-key, akamai-x-get-true-cache-key, akamai-x-get-request-id"
