Amazing thank you for the update

A beta version will be released in few weeks.

Saw that a fix had been implemented for this in 6.2, is there an estimated release date for it?

Thanks for your report.

I have added this issue to the tracker:
Issue 2191 – WebDAV or S3 certificate that is recognized by Windows Certificate store, but have other issues, cannot be marked trusted by the user

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

Hey!

When doing anything with my files in a S3 storage, I get a "Certificate not trusted" warning EVERY single time, for every single file. Clicking "Yes" does not seem to save my preference. I have logged the session, but do not feel comfortable posting the log publicly, since I don't know how much sensitive information I could potentially leak :D.*

Edit: I just skimmed through the logs, doesn't seem like there is anything relevant, so I added the log file.

Have a great day!
