Handle Gracefully when Etherscan.io API goes down

[EbenezerGH]

Experienced an etherscan.api network outage for the first time and the module wasn't able to handle the crash gracefully. After 10 seconds the stream crashes.

Caused by: java.net.SocketTimeoutException: failed to connect to
Caused by: java.net.SocketTimeoutException: failed to connect to api.etherscan.io/23.111.151.66 (port 80) from /192.168.1.3 (port 37860) after 10000ms

**Should also handle gracefully faulty connections
