I want to add LE cert to my Synology NAS device with the DSM built-in wizard, but during the setup I got “The operation failed. Please log in to DSM again and retry” error message. I have 80 and 443 ports open and forwarded. In my browser my site loads successfully.
I checked the /var/log/messages file, and that’s what I found:
synoscgi_SYNO.Core.Certificate.LetsEncrypt_1_create: certificate.cpp:957 syno-letsencrypt failed. 200 [new-cert: Unexpect httpcode. (new-cert)] synoscgi_SYNO.Core.Certificate.LetsEncrypt_1_create: certificate.cpp:1359 Failed to create Let'sEncrypt certificate. [new-cert: Unexpect httpcode. (new-cert)]
My DSM verison is 6.1.1.
What did I do wrong?
