I am facing an issue, The erpnext website cannot be accessed thru a set of computers on one wan ip, but at the same time I can access it from computer which has a different wan ip.
Initally I thought it was a local network issue, but now after digging around, I think that access to the frontend (nginx) is being denied,
I have enabled Fail2ban and UFW, In the firewall I have opened ports for SSL, HTTP, SSH and Postfix. Fail2ban jail is configured to look at SSH connections.
Am I overlooking anything?
