Mikrotik+parts of sites

Hi to all guys!
Im have next problem:
Im have stable internet connection and all working correctly expectation is in some sites, nvidia.ru for example, while it pings succeful it not opens in browser (ERR CONN TIMED OUT for chrome)
I was asking my internet firm but they dont know which problem it can be.
If im using VPN, or some proxy stuff all work good, but by direct connection im cant receive some sites in browser(at any kind of device - ios, android, win7, win10)
srry if my english rude sometimes.
im can give to u any configuration screenshots

Are you using EoIP for anything?

ask your ISP to change the route of your connection.

Ask your ISP to refresh your connection and route it again. It will work fine then
