@Xykon Telia allows tcp/ip mqtt access.
It was as I suspected, a DNS server issue. I solved it by modifying the pybytes source code to use Google DNS.

time.sleep(3)
print_debug(1, 'LTE init(carrier={}, cid={})'.format(lte_cfg.get('carrier'), lte_cfg.get('cid', 1)))
And also need to reset modem on boot-up, because otherwise it can hang when connecting to the MQTT server, for whatever reason (?):
# boot.py -- run on boot-up
from network import LTE
print("Resetting modem...", end="\r")
lte = LTE()
lte.reset()
lte.send_at_cmd('AT^RESET')
print("Resetting modem... Done.")
I have to disable pybytes autostart in the json file, to get this working, obviously.
