Ubuntu 16.04 LTS VPS
letsencrypt --apache --rsa-key-size 4096 -d xxx.online -d www.xxx.online -d yyy.xxx.online
ConnectionError: HTTPSConnectionPool(host=‘acme-v01.api.letsencrypt.org’, port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError(’<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7fe72a6a3590>: Failed to establish a new connection: [Errno 110] Connection timed out’,))
Reading the last lines of my log file, it seems that I exceeded a Retry Limit.
Strange thing is that I never actually received certificates.
The same request for other domain names function normally, only this .online domain name refuses to register.
Can anyone shed some light on this?
