If your tea has an expiration date then it's just for best quality, not safety. I've personally found tea bags sitting at the back of the pantry that were more than 3 years old, the packaging had even started to fade, and the tea was still fine. I just had to steep it for a little longer.
Depending of the variety of green tea it should be brewed around 175 degrees F (79 C) give or take 5 degrees. This can vary on the variety so be sure to check that carefully. You started off with old green tea. Green tea, when properly packaged, has a shelf life of about 6 months. Once opened you have about 2 months to use it. That's for properly packaged (vacuum packed or nitrogen packaged) tea. If your green tea wasn't packaged properly and is exposed to any amount of air, it probably was never good to begin with.
