I'm getting this error from the docker log with a 10 freqtrade instances test after 3h

and i have been seeing a teapot message on another FT instance, so i guess i was IP-banned. can we have a better error handling / check if ban or maybe even an output signalling the current API weight / or think about throttling it down somehow?

The IP ban issue is not related to the proxy, the proxy itself does not do any API requests after the initial ticker data is loaded (so once you start it, it will make one request per pair, after that we rely on websockets). The latest commit fixes the specific issue you had.
