TMDB getting 401 and 403 errors

I am running Kodi 16.1 with TMDV version 4.0.2.  I know I'm on old versions, I hate updating things!  I just wanted to see if I could fix this as is or if an update would even help.  It also mentions cache problems, but seems like the connection issues are causing the cache issue, not creating it.  Here is my log, any help would be greatly appreciated.
