Hi there, hoppers!
This is an internal error on Binance. The Hopper is just reporting it.
The letters after checkpositions on: can change. They could be EH or FP or whatever.
It means the server is getting too many requests and is locking us out. The hopper will change server and try again.
If this error happens sporadically, ignore it. If it is constantly happening and your hopper is no longer working, please send us a support ticket.
