Hi Guys,
We have been working with Ethereum Ropsten network for the last since months and everything has worked like a charm. Since 2 days ago, suddenly it not worked anymore.
Checking the code we found that we are being blocked from Cloudflare and we are getting the following exception:
Please enable cookies.
Error 1020 Ray ID: 51da023f6e626cda • 2019-09-29 00:58:27 UTC

About the problem we consider that its an external problem from Ropsten and we would like to know your feedback with this security access problem.
Kind regards,

Hi Guys,
I have found a solution. If you face this error just add a header in all your request to this API https://ropsten.etherscan.io/api (It took me more than 2 days found this which is really simple) … Additionally, you can add your API KEY https://etherscan.io/myapikey.
File=cert_issuer/blockchain_handlers/ethereum/connectors.py
headers = {
‘User-Agent’: “PostmanRuntime/7.17.1”,
‘Accept’: “/”,
‘Cache-Control’: “no-cache”,
‘Postman-Token’: “267dd7be-7f3f-4d67-a51c-05152aa8e8fc,8f8b84b0-3df1-4656-9480-c31e99d270d2”,
‘Host’: “ropsten.etherscan.io”,
‘Accept-Encoding’: “gzip, deflate”,
‘Cookie’: “__cfduid=d33064099a72a08ae6f9197c790da62d21569724532”,
‘Connection’: “keep-alive”,

}
response = requests.get(broadcast_url, headers=headers)
Added a new ethereum api, myetherwallet, to the mix. Should be resolved. In version 2.0.20 if you’re using pypi.
