Twitter widget feed (also newly made widget) does not show tweets since january 14th


My twitter feed stopped refreshing since january 14th, made a new widget but same result, any solutions?
see for embeded widget-feed and see my twitteraccount to see there are 3 newer tweets.
Even the tweet on january 15th doesn’t show.

I deleted the old widget and made a new one and embeded this, while making widget the new tweets don’t show up in the example screen.
searched here and google but found no solution.

something must be wrong…

Anyone any suggestions?
