Problem in viewing the IP through http

I am connected to another network through L2TP, one of the IPs in that network is 192.168.6.63, for example, I have the ping of IP 192.168.6.63 in my system, but I cannot see it in my browser through http.
Pay attention, when I make the connection manually in my system, I can easily access it through the browser, but when I connect to the connection in Mikrotik, I have a problem.
