cert_issuer.errors.InsufficientFundsError: Please add 500000000000000 wei about cert-issuer HOT 6 CLOSED

I am not too certain of the deeper issue there, but to put you on the right tracks, I think the error comes from the connection error with the RPC:

INFO - Getting balance with EthereumRPCProvider
WARNING - HTTPConnectionPool(host='localhost', port=8545): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f06ddbf8198>: Failed to establish a new connection: [Errno 111] Connection refused',))

I haven't spent a lot of time in this project so I don't know all the internals on top of my head, but you might want to look at which ethereum RPC is being called and if you need to provide an account for it. What really catches my attention is this: Max retries exceeded with url: /. I don't remember if you need to configure it manually.

Hey @lemoustachiste ,

Thanks for you reply,

You mean i need to increase the value of max retries

from cert-issuer.

Please take a look at #206.
Also you may configure your own RPC provider:

If anyone else is facing the same issue
Clone the old commit commit sha_id c3c7233

@lemoustachiste this resolves my issue

I am now also facing this issue, I have opened a ticket with Etherscan to understand why the API sends back a captcha challenge.
At this time I recommend using another rpc provider to issue with Ethereum

from cert-issuer.

Ok the fix is to provide User-Agent headers with the request. I have a local fix in the v3 branch, I'll see if I can put it in master too.
