I'm trying to connect by WebDAV protocol in new version 5.21.1, but it's occuring an error.
When I used to connect in 5.19.6 there wasn't any problem

Re: Digest challenge not supported

Thanks for your report.
WinSCP 5.21 indeed does not support legacy RFC 2069 Digest anymore.
What server are you connecting to that still uses it?
