The cerificaat on my Synoloy NAS has been expired.
I ran this command: /usr/syno/sbin/syno-letsencrypt renew-all --vv.
It produced this output: nothing
My operating system is (include version): Synology DSM 6.1.3 build 15152.1
My web server is (include version): Integrated webstation?
Problem:
I had port 80h forwarding (used for creating certificate) disabled, so NAS was not able to automatically renew the certificate. Before renewal I have enabled this forwarding
I was not able to save the output, but the error was 403. (At the moment I’ve done too many attempt so I have to wait for my retry counter to be reset).
Actions:
I’ve forwarded port 80 in my Router to port 80 of my NAS.
Additional info:
I’ve tried with ZeroSSL also, but the file which must be copied to ,/well-known/acme-challenge can’t be accessed.
Default an index.html file is supplied by Synology webserver. Accessing mynas.com works fine.
For test I’ve created directory ./well-known and placed the index.html file here. I can acccess mynas.com/.well-known
I’ve create ./well-known/acme-challenge and placed index.html. I can NOT access mynas.com/.well-known/acme-challenge.
My questions:
Am I right the redirecting port 80 to NAS port 80 is only requirement? Or should I forward other ports?
Why can’t I access the acme-challenge directory?
