I ran into the next error with market-arbitrage.py. This error sometimes comes up and sometimes not

This is a safety measure when the price of a sack of gems cannot be retrieved: the status code of the response is not 200.

Unfortunately, this usually means that you have reached Steam's rate limit, in which case there is little we can do about this.

Your best action would be to try to manually update the values of the cookie. However, as you mention that the error does not always happen, then this is most likely due to rate limits (and a temporary ban for too many requests) rather than obsolete cookies.
