On thisnetwork where I am now there is no such entry:

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "resolvectl status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.

# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
options edns0

but the problem is the same.

On the bright side this changed the client and now it caches the resolved ip and connects with ip not the name... but this is an ugly patch and it fixes only one service. All other services are slow. That is interesting is that using mdns4 with mdns.allow fixes the issue sometimes not always. and sometimes it is even slower...
