[zjesko]

Environment

Testnet

Provide a brief description of the functionality you're trying to implement.

Trying to do normal function calls on zksync sepolia testnet

What is the specific issue or error you're encountering?

https://chainlist.org/chain/300

All of the above mentioned RPCs fail all at once sometimes and starts working again. This happens on interacting with not only our protocol but other protocols on testnet as well

Can you share the error messages or logs you're receiving, if any?
