Thank you for your feedback, I use the standard ports.
But if it was a port issue, I wouldn’t be able to access from my mobile phone over data, at the same time other users were getting page not found after a while they got to login but got page not found in 2-5 mins. It felt like a firewall was pushing them out.
I will check the ports and confirm, I post my findings
After doing a lot of digging around, I see that in the install script a fail2ban jail for nginx is created, This jail blacklists user with a particular IP, if under NAT all the users are locked out for 10 mins.
Is there a work around without static IP and disabling fail2ban jail?
I am testing and looking for options will post my finding
