NAS: Synology DSM 6.2.2-24922 Update 4
Client OS: Windows 10 1909
My Synology didn’t renew the certificate automatically. I do not know why. Manual renewal was not possible. Tried everything possible for 3 days. Always error messages. Deleting the old certificate entry did not help either.
Then I applied Michaelbierman’s tip.

“So I went to Control Panel> External Access> Advanced in Synology and reset” hostname or static IP “. It seems to be working now. Very strange, but I think I’m fine now.”
Certificate requested again. Error message: “… please register again at the DSM”
I registered again on DSM. Now I see 3 certificates with the expiry date 2020-04-15.
Which of the displayed certificates should I use now? Can the excess certificates be deleted?
Sorry for my bad English.
