I have 4 DCS cameras connected on my network primarily to detect motion while away from my residence for 4 months. All was working properly until March 19, 2020 while I was away. Motion was being detected and emails were being received to that effect. However, there were no emails that would contain the images and video. My email for receiving messages is Yahoo Mail. No passwords were changed, nothing was changed. I have checked yahoo mail for the proper security settings and all looks correct. (Just a note, my cameras are DCS-932L, DCS-933L (2 of them) and DCS-5010L). I am wondering if something changed in Yahoo Mail that is preventing these emails from coming through, but in all of my research on the Internet, I can't find anything.
All cameras can be viewed/manipulated properly with Internet Explorer or on mydlink lite app on iphone.
As a side note, when I access the setup with MyDlink.com, in the Setup, I do a mail test and the status says "No test conducted" and "Invalid username/password". The puzzling part is that I am receiving email notifications of motion and email notifications of when the cameras are disconnected.
Additionally, my router is cycled in the middle of the night in order to prevent problems.
I am completely lost at this point and any help would be greatly appreciated. Thanks, Mark
