In Windows 10 Pro 20H2 19042.804 64 bit the Chrome and Edge browsers shows invalid certificate, "Windows does not have enough information to verify this certificate." However, in Opera browser it shows black lock and says certificate is valid. Access is via the standard Synology xxx.synology.me or quickconnect.to/xxx domains. Since Opera works, it appears that Windows 10 trust center, which is linked to Edge and Chrome, doesn't honor Let's Encrypt certificates properly. Is there a fix?
I am able to access it from my PC in various browsers, but not secure except in Opera. Chrome shows the cert info but it is not trusted by Windows. I do not know why you are timing out. The target is a Synology NAS attached to my router. I am using a laptop attached to the router via Ethernet cable.
I had put the site as trusted to stop the warning. I took it out of the trusted sites, but now I don't get the full warning anymore with the button. It may require a restart.
Thank you very much for your kind assistance. I will pursue this with Synology. For some reason it looks like they are somehow relabeling the cert. Opera doesn't mind, but Chrome and Edge do. Kindly see if you can reach quickconnect.to/leojbourne since the other domain site times out.
The Synology NAS installed Let's Encrypt certificate configuration points by default to synology.com instead of .synology.me or a trust chain, which makes certain browsers show invalid certificate. This setting is in an obscure location.
Login to the NAS as administrator, and then click Control Panel, then Security, then the Certificate tab, then highlight the desired certificate (usually it should be the default at the top of the list), then the Configure tab, then at the right side click each of the down arrows for the various apps and instead of the current synology.com pick .synology.me. Click the OK button and suddenly Chrome and Edge will start showing a lock icon for secure transmission. It is possible that a discussion of the setting appears somewhere in the Synology instructions, but I didn't see it. Maybe this information will help someone.
I appreciate the quick, expert assistance from the forum.
For some reason things in angle brackets are removed when posting, and I had the word "account" in angle brackets before synology.me, but it did not show. The format is the standard accountxxx.synology.me.
