A couple of days again the command line client I use to run my Twitter accounts TTYtter stopped working. I finally had a chance to explore why and discovered it was due to the fact that twitter have moved to SSL only.

So if you are running TTYtter 2.1.0 and getting the error message,

*** warning: timeout or no data

then starting with -ssl or putting ssl=1 in your .ttytterrc may fix it (thanks to @tjh for the fix).
