With new Let's Encrypt certificate, "Check For Update" failed.

Hi!

I tried to update WinSCP 5.8.2 beta (build 6284) via "Check For Updates" but winscp.net has new Let's Encrypt certificate, so, it's failed because of certification trust. (look attachment)

Description: Error

Thanks for your report.
Is it Windows 10? What build?

I cannot reproduce the problem.

Does your web browser (which one?) trust the new certificate? Try the Edge or Internet Explorer too.

Windows 10 Pro, Version: 1511, OS Build: 10586.318 (I'm updating my OS).
Domain winscp.net in Google Chrome and Internet Explorer which use central "Trusted Root Certification Authorities" is trusted. (look attachment).
That is the weird thing...

Please try to connect to the https://winscp.net/, as if it were a WebDAV server and attach a Debug-2 level session log file.

I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
