[OFFTOPIC] WIN10 issue with site-to-site VPN

Hi All,

I have a working site-to-site VPN between A and B sites. There is a single Win10 box in A site, where I can not make HTTP traffic from B site for some reason.

All the other Win10s works well.

This PC however CAN ping the peers in the B side, I can telnet to port 80, it is able to connect, but the webserver does not serves it for some reason, but it does the other PCs.

I know that this is offtopic here, since I don’t know Windows, maybe there are a few experts here what to check on that specific box..
We would like to understand what is happening with that box…

The obvious things were ruled out. It is NOT a firewall issue, not caused by an antivirus app etc…

Any comments are welcome..

Thanks in advance.
