Describe the bug

Starting today, getting strange intermittent errors on forge test. It seems to be related to fork environments. Different sets of errors:

This error occurs 1/3 times:

2022-09-15T17:16:42.272914Z ERROR sharedbackend: Failed to send/recv `basic` err=GetAccount(0x1804c8ab1f12e6bbf3894d4083f33e07309d1f38,

Another 1/3 times. Infura seems to be working properly (can fetch block number and blocks via cast no problem):

Could not instantiate forked environment with fork url: https://mainnet.infura.io/v3/<projid>

Context:
- Failed to get block for block number: 15540530
latest block number: 15540530

Very strange one, tests run but with weird errors and using astronomical gas

this is thrown when we failed to retrieve the account data from the provider,

the actual rpc error message is "message: header not found" I have seen this a few times today, with infura

The mainnet enpoints were changed from https://mainnet.infura.io/v3/key to https://user:key@eth2-beacon-mainnet.infura.io but getting same intermittent issues with the new one. I just switched to Alchemy and all good

@mattsse i think there is no action item for us here, is there?

[mattsse]

we're now retrying the request when we see this error:

gakonst/ethers-rs#1706

header not found

should be resolved now
