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.
My domain is: pettyphoto.com
For sometime, I’ve had a letsencrypt cert installed on my Synology NAS and it’s working fine. I thought that I’d followed the correct steps to copy the same cert on to my new Synology router, as it worked for a few weeks. However, it’s now expired, but the version on my NAS continues to automatically update.
I’m pretty junior at this whole encryption certificate thing, and would appreciate any input and help that you can provide in getting the cert on my router working and auto-renewing.
