safe-hub.miningpoolhub.com is working albeit the delay-ness. But at least its working. Keep up the good job!
Edit:
There are more rejected share, alongside the stratum_recv_line failed & stratum connection failed.
The reason for rejected share is low difficulty of the share. I didn't force the difficulty target.
Yeah I'm working with third party ddos protection service and it's getting better daily.
Thank you for your report.
