FRR in Eve-NG lab - Can't get remote address and port

[bcrawfo2]

I'm using FRR (10.2.1 running on Alpine) and trying to establish BGP to a Velocloud SDWAN device in my Eve-NG lab.
I had BGP working between Velocloud and an Aruba switch and want to replace the Aruba with FRR using same ASN and IP.
Configuration is pretty simple. I see in the FRR logs "Can't get remote address and port: Socket not connected"
"Show IP bgp summary" shows "connect" and no messages sent or received....presumably because the TCP connection doesn't establish.
I used this same FRR install to point to a different BGP speaker (a Ubiquiti gateway) and was successful.
Google doesn't give me any info about the socket not connected error.
Any thoughts?
