Looks similar to [Access Denied - Ethereum Ropsten](https://community.blockcerts.org/t/access-denied-ethereum-ropsten/2107/2) Confirmed this is happening to me on ropsten but mainnet works. I tried adding an API key but it is still blocked on ropsten. I’ll open up a ticket on this and can hopefully get around to adding another ethereum API this week. ---

Added a new ethereum api, myetherwallet, to the mix. Should be resolved. In version 2.0.20 if you’re using pypi. ---

500 trillion wei is only 0.0005 ether. What’s the problem? ---

Not sure, not seeing that problem myself. Typically it comes from either incorrect settings or the inability to access ethereum API’s. Could you post your config & logs? ---

Looks pretty similar to this: [Access Denied - Ethereum Ropsten](https://community.blockcerts.org/t/access-denied-ethereum-ropsten/2107/2) Do you have version 2.0.20+ of the blockcerts issuer? ---

Yes, first thing i did was to get the latest version but i still get the error. ---

Could you double check that the latest is actually running? Distinct in the logs should be something like ```auto INFO - Balance check response: {'jsonrpc': '2.0', 'id': 1, 'result': '0xda8fa4202ab0000'} INFO - Balance check succeeded: {'jsonrpc': '2.0', 'id': 1, 'result': '0xda8fa4202ab0000'} INFO - Total cost will be 500000000000000 wei INFO - Starting finalizable signer ``` after the cloud front error. MyEtherWallet should be checked as a fallback when Etherscan fails. Otherwise `Error getting balance through MyEtherWallet. Error msg:` would display if it was having a hard time connecting to MEW as well. ---

I can’t see any of this in the logs. Can you elaborate more on how to check if the latest is running?
