Please help,
I use SRBMiner-Multi 0.6.5 for mining Haven (XHV) coin on haven.herominers.com.
After some time an error occurred: "couldn't connect to a devfee pool for a long time ... pause mining"
After that I have to restart the miner to continue working.
Your firewall/antivirus is blockin miner from accessing the devfee pool probably
When the miner connects to devfee pool and what is its address?
The firewall should not be a problem because it leaks properly haven.herominers.com.
