Helo,
Im trying to running cryptocurrency pool, but I face problem in firewall i think. I was open port using ufw its set allow, but when i cek from nmap, port stiil close. what i’m mising. Everything going well and run, so i think the main problem is firewall.

Blockchain full sync, everything running well and set in crontab (non password, so everything run):
@reboot sudo bash yiimpinstallscryptubuntu18.04/ screen-scrypt.sh
@reboot sudo bash yiimp

@reboot sudo /var/web/loop2.sh
@reboot sudo /var/web/blocks.sh
@reboot ./elicoin/src/elicoind
@reboot sudo /var/stratum/run.sh yescryptR16
