Hello, I wanted to renew this certificate over my Synology NAS /expired last year) that didn’t work. I deleted the expired one on my Synology and wanted to create a new one but it says I cannot have another one. Is it possible for you to delete my old request so I can create a new certificate? R…

Welcome to the Let's Encrypt Community, Annika :slightly_smiling_face: Given the fact that ddns.net is on the public suffix list and having examined your certificate history , I am unable to determine why you cannot get another certificate. What exactly are you seeing?

I tried it again, now it says it cannot connect to Let's Encrypt. but 80 and 443 are configured for my Synology at my router

Both Let's Encrypt and I are currently seeing port 80 as closed for NJDS15.ddns.net. [image] Test result for njds15.ddns.net: Error 2 unique issue(s) detected (ANotWorking, IssueFromLetsEncrypt)

Are you sure that port 80 is open externally in order to reach your NAS? Can you reach your own NAS from outside your network?

I ask this because I'm seeing a private IP address (192.168.x.x) for your NAS.

I configured DynDNS on my router Loks like it doesn't work...

I was suspecting a NAT/router issue.

Do you have full control of the network mappings from your NAS all the way to the public IP address (87.123.200.8)?

what do you mean with full control?
