How can it be fixed?

Network parsing should let me use ethereum:mainnet:http://localhost so that I can use the default etherscan explorer to pull up contracts. or let me programmatically specify an explorer when connecting to a local node. The long event query shouldn't crash, possibly due to rate limiting? The fact that this works with my bitchin rate limit retry PR for ape-alchemy makes me think we should have retry logic for all networks.

APE-1670 crash on long event query after refusing to connect to localhost

ah, this was a regression from the default public node work (i can see the bug). Pr soon.

[antazoey]

as a temporary work-around I think if you switch the port it will work, but i do have a fix incoming
