TVDB Unable to connect

Hi all,
First of all sorry for the noob question. I’ve just started running Kodi on a raspberry pi 3. The moviedb scans in all my movies no problem.On my first run of the tv scan it picked up 49 shows. Most of my tv shows though have not been picked up, I keep getting a message saying unable to connect to remote server. I saw in another thread that rather than scanning the entire folder(s) I could scrape individually? How do I do that? Will this issue persist or is it temporary?

Thanks
