Talking about network issue it could be also a very common arch issue with hostname resolution:
Avahi provides local hostname resolution using a “hostname.local” naming scheme. To enable it, install the nss-mdns package and start
avahi-daemon.service
.Then, edit the file
/etc/nsswitch.conf
and change thehosts
line to includemdns_minimal [NOTFOUND=return]
beforeresolve
anddns
:
hosts: ... mdns_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns ...
