Error donating from faucet with non-typical network configuration

[nieznanysprawiciel]

Faucet first resolves DNS using google resolver and later makes a request.
@markmooij has network configuration with DNS proxy setup-ed. This causes following error:

Error donating from faucet: CustomError: Error getting response from faucet Failed to connect to host: Connection refused (os error 111), /home/runner/.cargo/git/checkouts/erc20_payment_lib-fcd8dbf40a49d5e3/4200567/crates/erc20_payment_lib/src/faucet_client.rs:138:22

My DNS is routed through my Pi Hole by default, but I omitted by defining DNS directly to 8.8.8.8 and 8.8.4.4 to surpass, still the same behavior
