Slowly tries to download, but hangs and connection lost.

Please translate to English or I need to close it...

Translated, sorry. So it currently hangs on NetDrive:

"Access to removed object is not impossible"

I'm using WebDavCloudMailRu project (https://github.com/yar229/WebDavMailRuCloud), it's forked and based on your code, so i thought it could be very related problem

Is it the same bug? If so, maybe not WebDrive, but NetDrive?

As for WebDrive, Ramon replied here a time ago.

Tested NetDrive with NWebDav.Sample.HttpListener: I have file "/temp/raid_mark_soft.png", but can't open/copy it. Folder and file name does not matter.

[Corak667]

Not the same bug. It's really Netdrive. (Frequently mismatching protocol half-name and this program names). Used them both long time ago,

[Corak667]

Seems it can be a problem with NetDrive itself, so it's better to inform their developers.

[ramondeklein]

I'll close this issue when it's not NWebDAV related...
