OSError ssl handshake?

Question

I'm new to python and I have trouble analysing the following errors. Does someone know why my script crashed?

I'm scraping the web for some data and everytime the scraper hits, the script writes that time into database (to check if the script is still alive). Every couple of days the script crashes.

Thanks in advance.
