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.

I set up certs for two domains on this server: fates.org and sevardin.com. I am able to renew fates.org, but sevardin.com began failing with the above after the first round of renewals. I have tried placing a readable file in $WEBROOT/.well-known/acme-challenge and am able to view the file from a browser.
The machine where these domains are hosted crashed a few days ago—but after the first failed renewal attempt—and $WEBROOT has changed as a result. This change did not affect fates.org’s renewal. (I restored the machine from a backup from the day before I had renewed the fates.org certificate.) I have checked and verified permissions for the domain, verified the IP address, and am currently able to call up https://sevardin.com with the current certificate.
I’m at a loss for what to try next. The certificate for sevardin.com expires on 6 March 2018.
