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), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

curl_post: GET https://acme-v02.api.letsencrypt.org/directory failed: verify issuer failed: /C=US/O=Let's Encrypt/CN=R3 (505)
