I have Smartphone Nokia Lumia 635 with Windows 10 Version 1607 build 10.0.14393.2551 PC Windows 10 1903 build 18362.418 Yesterday I was connect without problem but today I can't connect - I see warning about certificate and I'm accepting risk but page has been refresh and show warning again and you can only accept risk and that's all - some kind of loop.

Looks like you're connecting to your device via IP address and not the name assigned to the device (that would be present in its certificate). Or it's self-signed and this never worked.
Can you provide a screenshot of the window that appears when you click the View Certificate link? A screenshot of the Certification Path tab would also be helpful.
