We have several proxy IP addresses to distribute our requests among them and prevent from being banned because of violating rate limits.
With Futures - this proxies work perfect
But we faced issues with Spot endpoints.
For example, proxy works great with placing orders, getting history of orders.
But when we try to connect to websocket - we receive “403 Forbidden” all the time.
And, there is no chance we have hit limits because we cant connect through any proxy of ours.
At the same time - same code works perfect without proxy. And same code works perfect to connect to futures with proxy.
Do spot and futures have different validations for rules?
Is there a place when we can find information about requirements for IP address? At least, countries, protocols, etc.
