How can i fix this problem?

[PhilippC]

are you on a reliable internet connection or could this be caused by bad wifi/data connection?

[x-plood]

Nope, i tried on my home wi-fi, on my work wi-fi, 4g connection on my phone, unfortunately the result is the same. However, through other apps, the connection and synchronization work fine.

Similar error here using webdav (https) on a different storage provider.

Same problem with webdav (https) and Yandex.Disk.

[PhilippC]

[Gigses]

Yes, on 1.06f and on previous version.

Fix is clear app data, add webdav https url again. And no more change keepass db on phone. :-/

[PhilippC]

tried to reproduce this but even failed to login with webdav, I get 401 unauthorized. Is there anything to configure in Yandex to make webdav work? can I use the same user/password combination used to login to the yandex site?

I use 2fa and i create separately password for program, also i use a https protocol to authorize. But login the same as the yandex site.

[PhilippC]

is https://webdav.yandex.com the right WebDav URL. I cannot connect through Windows Explorer either.

This way:

Unfortunately Yandex is unofficially blocking file uploads using this protocol now.

[PhilippC]

sounds like this makes it impossible to support Yandex through webdav at the moment
