I use the Let’s Encrypt Stand Alone add-on in conjunction with portmap.io. This has been working very well for me, however I am getting close to needing to renew my certificate, and I am now getting an error when running it.
starting version 3.2.4 Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator standalone, Installer None An unexpected error occurred: ConnectionError: HTTPSConnectionPool(host=‘acme-v01.api.letsencrypt.org’, port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError(’<urllib3.connection.VerifiedHTTPSConnection object at 0x75b9c4f0>: Failed to establish a new connection: [Errno -3] Try again’,)) Please see the logfiles in /var/log/letsencrypt for more details.
I have seen other posts about this being a dns issue, but I am able to curl the url no problem from the ResinOS.
