I'm using Python 3.4 on a Raspberry Pi to upload weather data to a website. Sometime there's a problem uploading (slow Internet or something) and my program crashes. I'm using try/except, but for some reason it's not catching the error. I thought the the last except statement should catch any other errors.
Here's the error:
