Suddenly episodes not being found though name correct

I am using Kodi 16.1 “Jarvis” on the nvidia shield tv and everything was working just fine but suddenly when I add an episode to my library that’s on my connected external harddrive it does not add the episode to my library when I update.
All the previous things from the external are there. Now here’s the od thing when I manually go to the external through the file system I can see the episode if I choose the submenu for it and click episode information than it updates and adds itself to the library. In the file the name is for example timeless – s01e07 and after hitting episode information it will change to s01e07.

Also I started to get a message “couldn’t download information Unable to connect to remote server. would you like to continue scanning?”
