Both have been working for years with no changes to password or account. Both stations still update websites fine. They are about 1,000 miles form one another on completely different ISPs.
I did have another "twitter stream" issue requiring all new java code for twitter streams to be imbedded as text into web pages. It appears this code also went bad around the same time.
I think it is possible that how you are interfacing with twitter is no longer valid.
What to do?
