I'm currently trying to run deploy a contract on the Sepolia testnet and when I run in the terminal the following line of code

brownie run scripts/deploy.py --network sepolia

after some minute I get the following error:

INFO: Could not find files for the given pattern(s).
Brownie v1.19.3 - Python development framework for Ethereum

BrownieSimpleStorageProject is the active project.

has anyone already had the same issue?

I already tried other testnet but in vain. The contract is correctly deployed using Ganache.

I Was Facing The Same Problem I Have Just Solved It. You Just Have To Change The Host Address in Brownie Network Config Maybe this host='rpc.sepolia.dev' is busy or down

You Can Find Other Host Lists From The https://sepolia.dev/ There Many Host Address. In my case this host https://rpc-sepolia.rockx.com/ worked..
