ospf_read invalid Area ID

Hello Community,

I have a strange issue with two VPN Tunnels and OSPF. For this tunnels the Firewall says that the Area ID 0.49.1.0 is invalid. On some other sites the Area works. 10.10.241.85 is the local firewall, the other firewall (on the other end of the tunnel) is 10.10.241.86. But in the election I didn't the 2nd Firewall:

2022/02/24 18:07:29Z OSPF: interface xfrm32:10.10.241.85: ospf_read invalid Area ID 0.49.1.0.

Has anybody an idea?
