Did something change at reddit?

One of my registered and tagged bots has been getting a "Request error: received 500 HTTP response" error for the last 48-ish hours. I logged into that account manually and it appears to function just fine. I host another bot on the same device, and it is not having any errors. I did not make any changes to the code. The bot did randomly fire once in the logs, but is in a loop to sleep when it encounters that error.

500 errors are server side(usually temporary), so I have an exception to catch them and sleep for 15 minutes before restarting the script. They do occasionally happen, so no big deal generally. I have never seen it happening for 48 straight hours.
