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.

We just switched off the RemoveWFE2AccountID functionality in production and are seeing issuance from sslforfree working as intended once again. Please also see the following topic ACME v2 - Scheduled removal of ID from account objects
