What version of lua-resty-auto-ssl are you running? And have you manually created or modified any of the files inside /etc/resty-auto-ssl/letsencrypt/? It looks the dehydrated Let's Encrypt client is failing during an openssl command to read a certificate file. It looks like people have run into this when the files have windows line breaks or the cert is in the wrong format. I'm not sure why dehydrated would be doing this under normal operations.

If you think the files might be corrupted, you could try moving aside the current dehydrated directory (sudo mv /etc/resty-auto-ssl/letsencrypt /etc/resty-auto-ssl/letsencrypt.bak) and then fully restart nginx (a fresh directory should get re-created), and then see if a fresh issuance will work.

Thanks a lot for the quick response @GUI. Much appreciated! Your solution worked but I also needed to remove all those KEYS from redis. We are using lua-resty-auto-ssl 0.10.5-1. As for you questions: We didn't modified those files manually. Maybe something else is causing it to fail. Let me know if you need more details.

Have the same issue several times – cleaning redis helps. Looks like when I had directory certificate storage, it worked successfully (but I am not sure), but after switching to Redis definitely did not work

This issue still comes when redis is used. Any permanent solution to this?

[adityapatadia]

Sorry my bad, it was due to us hitting certificate issue limit.

any update on this issue I am also getting into the production environment thanks in advance.
