"Reset by peer" connecting to Let's encrypt API from Singapore

I have a instance on AWS EC2 from Singapore. When my program called the API https://acme-v02.api.letsencrypt.org/directory, I got TCP connection reset.

My IP is 13.215.223.218 or 18.136.12.145

I tested mtr and curl, and here is the information I tested.

[root@console ~]# curl https://acme-v02.api.letsencrypt.org -v
* About to connect() to acme-v02.api.letsencrypt.org port 443 (#0)

Welcome to the community @sam_skycloud

I moved your topic to the Help section.

Normally you would be shown a form to fill out but I think your post is clear enough. Interestingly, another poster also complained of "reset by peer" from an AWS EC2 Singapore server.

Does this problem continue? There are temp errors that can occur and I don't know of any outage. Your two posts may just be the first to discover the problem. But, would be helpful to know if it repeats. Thanks

The poster at the other Singapore thread reports the problem has cleared.

Is yours also resolved?
