This is my topology:
PCMitarbeiter and PC1 are in the same VLAN (Mitarbeiter)
PCMitarbeiter ip is: 143.54.234.1 and PC1 ip is 143.54.234.2
configs:
MLSA:

I guess you need to give bit more information on this.
From the running config the two devices are connected in different switches. So the communication should be via trunk.
Can you let us know the short topology of this with interface name and the running config of those interfaces connected?
Additionally the "show int trunk" output of your trunk interface to see if the vlan is allowed on it.
Might also need to verify if the spanning tree is in forwarding state. "Show spanning-tree vlan <>" on the switches will help.

Thanks @Naresh Murali . I did show vlan on MLSA and saw I forgot to add the vlans on there. Everything now works as expected.
