Wireguard is not working - 24.1.7

[abbinett]

Wireguard stopped working since version 24.1.6. I verified the keys both on mobile, and laptops (see the wg config below).  The error I'm getting is  "[NET] peer(WVSy…H7jQ) - Handshake did not complete after 5 seconds, retrying (try 2)". The internet suggested to recreate the instance and its peers, and rebooted but that didn't help.

Opnsense version: OPNsense 24.1.7_4-amd64 installed on baremetal

See my firewall rules for the WG and WAN interface:

WAN:

WG

What did I do wrong?

The verified the keys much in the instance and its peers:

root@router:~ # wg showconf wg0
