Web3 Error: Geth Could not transact with/call contract function

Question

I decided to run my own ethereum/bsc fullnode. I downloaded geth-linux-amd64-1.1.0 and ran it like this: geth --syncmode "full" --http --http.port 8545 --http.corsdomain "*" --http.addr "127.0.0.1" --http.api "admin,debug,web3,eth,txpool,personal,ethash,miner,net" --cache 18000 --maxpeers 500 --datadir /someplace

geth attach and eth.syncing shows me

{ currentBlock: 9606766, highestBlock: 9606883, knownStates: 345833179, pulledStates: 345782057, startingBlock: 9604320 }

So i guess i'm synced. However, when i run w3.eth.getBalance(some_address), it returns 0. When i use Metamask or infura, i get a different value.

I'm also unable to interact with tether on ethereum (or any other token):

ERC20_ABI = [..] tether_contract = w3.eth.contract('0xdAC17F958D2ee523a2206206994597C13D831ec7', abi=ERC20_ABI) tether_contract.functions.balanceOf(that_address).call()

Result:

        raise BadFunctionCallOutput(msg) from e
    web3.exceptions.BadFunctionCallOutput: Could not transact with/call contract function, is contract deployed correctly and chain synced?

What am I doing wrong?

It's always ~64 block behind the network for a long time. (even with NVMe)

{ currentBlock: 9606766, highestBlock: 9606883, knownStates: 345833179, pulledStates: 345782057, startingBlock: 9604320 }

So i guess i'm synced

Actually, this means your node is still syncing, eth_syncing will return an empty result when it is over.

https://eth.wiki/json-rpc/API#eth_syncing

An object with sync status data or FALSE, when not syncing
