I have installed aapanel on Ubuntu 18.04 and 20.04, the installation done successfully and I have opened all the needed port, however I'm not able to access the panel and when I checked the IP address I found that port 8888 is closed!
Although if I installed aapanel on centos I can access it, both VMs are on the same firewall so I'm not sure what's wrong with Ubuntu.
Thanks in advance for your help 🙂
