IPSEC tunnel traffic issue

Situation:

We have a site2multi-site situation. The main site A 10.10.0.x and secundary site B 10.10.16.x .

Printer 10.10.16.230 directly connected to the firewall.

Site2site with IPSEC vpn tunnel

Policy:

Site A -> Site B allow any

Site B -> Site A allow any

No antivirus or anything enabled

Problem:

When we try to surf to a printer or switch webconfig page from A -> B the browser shows http://10.10.16.230/index.html  but it keeps loading. @Site B we can browse perfectly fine to the webconfig.

Noticed:

- Ping works in both ways

- RDP works from B-> A if we disable IPV4-Offload (NIC computer)

- DNS server @site A, so the client computers @siteB can surf without any issue through dns server(A)

- Other sites are not having this issue

- The printer cannot send mail from site B -> Mailserver Site A

Already tried:

- Remove ipsec tunnel and created a new one

- rebooted firewall @siteB

- disabled/enabled auto-asic on all policy's (A + B)

Does anyone have a clue what this could be? We dont know where to look
