web server without access through VPN Site-to Site

Hi everyone, I am having a problem these days that we can summarize: I have a site-to-site IPSEC tunnel Site-to site between office (A) and office (B) that connects 192.168.30.0/24(A) networks with 192.168 .10.0 / 24 (B) the VPN is closed without problems, but I have a webserver running in office (A) that I can ping and access ssh, but I can’t access web (80 or 443) in office B (the ports are configured correctly on the webserver firewall). In the last tests I did, I found that I can access this web server if it is connected with the VPN site-to-client (ovpn) at office B that gets the same ip from the internal network that was closed with the office A (192,168 .10.0 / 24). I have rules/NAT that accept the connection between this networks :

src-nat souce 192.168.30.0/24 to dst 192.168.10.0/24 action accept
src-nat souce 192.168.10.0/24 to dst 192.168.30.0/24 action accept

I really appreciate if someone can help me, thanks
