Hello,
I’ve been running an API-based trading system with Binance for the past 3 years. However, for the last 2 months, I’ve been intermittently receiving the following error:
APIError(code=0): Invalid JSON error message from Binance: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

This happens only occasionally (once every few days), despite my system making regular hourly API requests. When the error occurs, simply retrying the request usually resolves the issue.
My questions are:
Is this related to rate limiting, or something else?
If it is rate limiting, shouldn’t the API respond with a standard JSON rate-limit error rather than HTML?
Is there a better way to handle this other than retrying?
Thanks in advance for any insights or suggestions.
