Question - what IP address / URL does the miner attempt to connect to when it reports a share? I can try pinging it to see if it's blocked.
You can telnet to it, which is slightly better because Ping can be blocked.
telnet rx.biblepay.org 3001
You should get a blank screen.
I got a blank screen initially, then I got this after a few seconds:
