WebDAV server blocks iPhone/iPad due to too many login attempts

Hi,

I have encountered a special problem for some time now and hope to get some advice here.

I use a WebDAV server on my Synology NAS to synchronize data between devices and apps which support WebDAV. So thank you for providing this solution for people who don‘t want to rely on the usual data storage providers for synchronisation.
To secure my server, I have an automatic block for IPs trying to login unsuccessfully 5 times within some minutes. This setting never bothers me except when using KyPass4 which manages to get blocked on a regular basis. As this means blocking of the whole device for accessing the NAS, it is quite a nuissance.

Does anyone else observe this behaviour? How can several unsuccessful login attempts by KyPass happen if at other attempts I can upload and download kdbx files using the same settings (which I don‘t change)?

Thanks for any help.
Fabian

Maybe there is a connection to this behaviour described by another user:

I am using Kypass-ios a few years now. It works great. Thanks for that.

Despite my compliments I have a strange 'problem' though. I am using WebDav on my Synology diskstation to store the .kdbx file. This is working well (though slow) but on my synology NAS I get a few errors everytime Kypass wants to download or upload the kdbx-file. Nonetheless Kypass seems to work without problems. I get the following errorlogs (where xxxxxx is the username and yyyyyy the name of a directory):
PROPFIND:Fail to get authorization line.
auth_pam: Permission denied
Auth_PAM failed: xxxxxx
user xxxxxx: authentication failure for "/yyyyyy/": Password Mismatch

Does somebody knows whats happening here?

Hello guys,

first - thank you for this great App!

I have the same WebDev-Problems like Fabian. Everytime when i refresh the App - or when the App tries to connect to the WebDav Server - i see one failed login in the errorlog of my Synology WebDav Server

User [XX] from [IP-ADRESS] failed to log in via [WebDAV] due to authorization failure.

The second connection seems to be succesfull. I think that the app use for the first connection the default login credentials and not the custom login credentials of the user. My firewall block the ip-adress after 3 failues within 5 minutes.

WebDav Settings:
HOST https://DOMAIN.DE:5006/path/to/the/directory/that/the/database/files/are/stored/
USERNAME myusername
PASSWORD mypassword

Please fix this WebDav bug.

Kindly regards!

I am glad more people are reporting this strange behavior with WebDAV which I reported already in november 2018. Probably this bug can be solved now. Thanks!

@RedBug,
Is this WebDav problem fixed in version 5.3? I do not find it in the 5.3 Release Notes.
