Problem uploading Sims Story on The Sims 2

I recently tried uploading a Sim Story of mine and a message popped up saying:

internet connection failed.

error code: 5

I don't understand why this message displays. I have an internet connection that works just fine (otherwise I wouldn't be typing this). I use verizon as my internet provider if that helps. Please let me know if you have an idea of how to solve this!
