Hostgator told me on a support call over a year ago that Windows 7 had issues with Webdav because of digest authentication. They also said that future versions of Windows would solve the problems with Webdav.
However Windows 10 is giving me the same grief. I don't know if the problem lies with Windows 10 or Hostgator.
Windows 10 typically loses the mapped Webdav connection on each reboot. I'll often have to reboot 8 or more times to get Webdav to connect. Each time I will run their connection script to connect. However Windows responds with an error that I can't access the network path because I don't have permissions.
I'm getting really tired of deleting the mapped drive and rebooting a dozen times.
The site uses cPanel and it is using digest authentication.
Update: I have migrated to a new provider that is much more up to date than my previous hosting company. The problems persist, so it doesn't seem to be an issue that is solely their responsibility.
Sometimes if I delete the connection before reboot, it can be reconnected afterwards. Sometimes it still takes multiple reboots.
