No routing after reboot and upgrade

[Harlekin]

Hi,
I am Christopher from Germany and I am more a network guy than a firewall guy but ended up with taking care of our pfsense.

I have updated to 2.4.5 p1 and after the reboot I am unable to reach any subnets or addresses apart from the pfsense's own interfaces (carp and vlan interfaces) and addresses in my current subnet.

I have deactivated "all packet filtering" but no change.
From the pfsense itself I am able to reach all subnets and addresses.
During the update and the reboot there was a second pfsense which should become the standby node but it is shut down now.
We have a couple of vlans/subnets configured, some openvpn servers, ipsec connections and 1 wan uplink.

After 4.5 hours of checking and reading a lot of discussions on the internet have nothing left to try.

Anybody got an idea?

best regards
Christopher

EDIT:
the states of all connections, apart of the ones to the pfsense itself, are listed as NO_TRAFFIC:SINGLE.

I restored a backup from March which worked. Seems like I configured something wrong and it only showed after the rebooot.
