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.
I ran this command: Add a new certificate >> Get a certificate from lets encrypt. This succeeded however I am still not able to get it recognized by different browsers…
It produced this output: NET::ERR_CERT_AUTHORITY_INVALID
My web server is (include version): unsure
The operating system my web server runs on is (include version): Synology DSM 6.2.3-25426
I can login to a root shell on my machine (yes or no, or I don’t know): I don’t know
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): yes
The link showed that we reached a system that is using a cert that covers the name “synology”.
Which means that we are able to reach your synology device; but the device isn’t configured to serve content via the name “mredard.diskstation.me”.
I suggest you read on how to add/change the names served by the synology device so that you can include the desired name.
I wrote to Synology support and they accessed my NAS drive to check what was wrong. They changed some settings regarding the certificate services, that were not active (or at least I couldn’t see them). Not sure what else they did but they did the trick.
Now the certificate works when I access from internet. However, I still have a warning message that the website is not secured when I access the NAS locally. Is that a problem or should I just leave it as is and not care about it?
