What is the issue you’re encountering

We have our own EVM blockchain testnet and we have an RPC node behind an certain URL. So far it was working great. We now migrated our entire DNS to Cloudflare, mainly in order to have DDOS Protection for our Blockchain RPC endpoints. In itself, it’s working great via Cloudflare. But when I enable Proxy, somehow the RPC seems to “break”: in every blockchain application or code, I then get “error: network not detected” (which basically means, the RPC does not work). When I switch off proxy again, it works again. Can someone help us: how can we protect our RPC endpoints from DDOS attacks without “breaking” them? Thanks!
