I have a problem when connecting to SharePoint WebDav on it own SharePoint server by public URL, It displayed authentication popup repeatedly, even authentication was successfully.


But I can access the URL from my local machine.

Do you have any suggestion for me?

It sounds like the loopback check problem. The methods for resolving this are described at https://support.microsoft.com/en-us/kb/896861 (the symptoms described here are slightly different to your issue, but I believe the cause is the same, and he same methods would resolve it).

Method 2 is generally good for a Dev or Test server, but for Production you should consider Method 1 (unless you understand and accept the security implications of Method 2).


Try this link. You can also use SharePoint Explorer.
