Cant login using Web Dav on a Synology NAS

Hi. I set up Net Drive 3 using Web Nav on a Snyology NAS and everything was working last night and tonight it isnt.

I can log onto another computer not on that network and I can connect with no problem.

The error is Login Credential Failed.

I tried with the user’s account and the main admin account into the NAS and still it wont connect.

Also I turned off Windows Firewall and stopped Trend.

I uninstalled Net Drive and rebooted and reinstalled it.

Its weird because it worked last night.

Any ideas?


Please check if your router is blocked by Synology NAS.

If so, you can add your router IP into Allow List.
