Segfault in libc error 5

Running Ubuntu 20.04
I initially installed with the ppa package local backups were working fine so I thought I’d add an internet client.
Setting up the client went fine but the minute it connected the server crashed with segfault in libc.

Jul 20 09:29:51 hostname systemd[1]: urbackup-server.service: Failed with result ‘signal’.

I tried compiling my own from source as well with the same error. Server 2.15

Any thoughts?
