Connection Timed Out connecting to VPNIP:PORT while using the same VPN.

[sevenz]

I'm having a weird problem, not sure where the problem comes from. I'm using MerlinWRT RT-AC87U.

I have a NAS with nextcloud on 192.168.2.140, using Singapore airVPN with MerlinWRT OpenVPN.

I have configured/portforwarded properly without problem, but when I try to connect from within 192.168.2.100's browser, I get a "The site can't be reached. 185.200.116.203 takes too long to respond."

I tried using my PC (192.168.2.98) which is connected to the same Singapore VPN as well, I get the same "takes too long to respond".

I manually enter 185.200.116.203:23232 from my phone (192.168.2.101) which doesn't connect to VPN, I can easily connect to 185.200.116.203:23232 and greeted with Nextcloud login screen.

EDIT: I manually entered all browsers with 185.200.116.203:23232

I wonder what causes this? Is it DNS problem?

I tried connecting from my laptop using Hongkong AirVPN, I can access it without problem too.

This is my setting for the VPN.


Sorry if the above is not very clear, what I'm trying to achieve basically to access Nextcloud on my NAS with Singapore VPN using my PC within the same Singapore VPN.
