Unable to connect to Samba share from virtual machine without restarting smb

I’ve got a Samba server set up on my computer with the following smb.conf:

[global]
        workgroup = SAMBA
        security = user
        map to guest = Bad User

        passdb backend = tdbsam
        printing = cups
        printcap name = cups

        interfaces = lo virbr0
        bind interfaces only = true
        guest account = nobody

[printers]
        path = /var/spool/samba
        printable = yes
        browseable = no

[LinuxHost]
        comment = Host SAMBA Server for VM
        path = /home/bob323/libvirt-shared
        guest ok = yes
        force user = nobody
        force group = nobody
        directory mask = 777
        writable = yes
        read only = no
        create mode = 0777
        directory mode = 0777

My setup is detailed in another thread:

but I’ll provide any additional details here if necessary.

Recently, I’ve been having an issue with my virtual machine not connecting until I restart the smb service. Is there anything I can check to troubleshoot what’s causing this? As soon as I run sudo systemctl restart smb the VM connects without a problem, but if I check the status of the service before this it says it’s active and was loaded successfully. There are a few messages underneath the regular systemd status output:

Nov 28 11:15:49 localhost.localdomain systemd[1]: Starting Samba SMB Daemon...
Nov 28 11:15:49 localhost.localdomain smbd[2575]: [2019/11/28 11:15:49.821046,  0] ../../lib/util/become_daemon.c:135(daemon_ready)
Nov 28 11:15:49 localhost.localdomain smbd[2575]:   daemon_ready: daemon 'smbd' finished starting up and ready to serve connections
Nov 28 11:15:49 localhost.localdomain systemd[1]: Started Samba SMB Daemon.

Any recommendations?
