Problems running second DU

[BGarcs]

Hi guys, hope you're all well.

I am trying to run a configuration based on 1 CU and 2 DU, each with its own USRP B210. The goal of this configuration is to implement the handover mechanism by moving the UE between the cells generated by each USRP. I am currently trying to deploy the 2 DU's and do a forced handover. The problem is that I can easily run the first DU:

Thank you very much for your help.
