Yeah, I’ve tried with other ports, and the situation is the same. That’s right, port 8080 is the default port, and that’s exactly why I’m trying to figure out what’s going on, because I’m not using it for access. I set my own port, which used to work until recently, but now none of the ports I set work, not even 8080.
From the local network, if I don’t specify the port, the browser gives me a message that access is forbidden (“Forbidden, you don’t have permission to access this resource.”), meaning I have to define the port (e.g., 192.xxx.xxx.xxx:8080). However, when using a VPN and specifying that same port, I can’t connect at all.
I can connect via the HTTPS port both locally and through the VPN.
I’m trying to figure out what changed, because I can no longer access the QNAP over HTTP from outside the local network. It’s frustrating.
I’m using MikroTik VPN, L2TP and OpenVPN, I get the same result with both when I try to access via HTTP port 8080.
But it’s not the port, since the port is open, I can access other resources (servers, VMs) on the same port if I want to, I just can’t access any QNAP.
