Webpages not Accessible

Hello. I have an IPsec VPN tunnel between my data center and my branch office. the tunnel is up and i can ping LANs from both locations. However,I cannot access some systems URLs that are located in the data center, although I can ping the server and telnet on port 443 or 80 from the branch office. I tried different browsers as well. block bogon and private networks check-boxes are disabled on LAN and WAN. I have created Any-any rules on LAN, WAN, and IPsec. Also, for instance, I can remote desktop to a server in the data center without any issues. Thoughts?

I've seen behavior like this with MTU problems. Consider sending pings of different sizes through the tunnel and see what happens maybe?
