'Nginx does not respond to specific client-public-ip

I'm configuring two Domains to host two websites: dev.example.com and test.example.com

I'm using Nginx as a webserver and my websites, dev and test, are configured with server_name directive as two separate websites sharing the same host Public_IP

  • When I connect to both domains using a VPN_Public_IP I get response 'websites' from Nginx as Expected

  • When I connect to both domains using my personal router Public-IP I only get a response from https://dev.example.com, while access_log of https://test.example.com shows this access_log which means the request has reached the server. But with empty error_log and no response in my Browser:

Personal_Router_Pub_IP - - [17/Feb/2022:07:02 +0000] "GET / HTTP/2.0" 200 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98 Safari/537.36"

Is it a Domain-blacklisting issue or Client-IP-blacklisting issue, and how to identify the problem here?

Yesh the issue was that the domain is blacklisted by Router ISP following the regulations of UAE where I reside
