Welcome to Microsoft Q&A Platform.
If previous version of Edge can recognize your self-signed certificate only Version 81.0.416.64 meet with issue, you’d better feedback it and ask for help from Edge community

Hi TeemoTang-2039
I find the problem Edge keep track on my certifcate examplens. If I don't use it for long time Edge reject this certificate. So I delete my Synology certifcate and create the same example.ns certificate. Export and import it in the MCC . I connect my site example.ns form here it is secure
Problem solved...
Thx Robert (PL)
