Device can't sync to sntp, gives up after 10 times

Good morning

For a mqtt device only I setup time component as sntp as well as a DNS server:

wifi:
  networks:
    ssid: "something"
    password: "somethingelse"
  manual_ip:
    static_ip: 10.0.210.3
    gateway: 10.0.0.1
    subnet: 255.255.0.0
    dns1: 8.8.8.8
time:
  - platform: sntp
    id: sntp_time
    timezone: "Europe/Zurich"
    on_time_sync:
      then:
        - logger.log: "Synchronized sntp clock"

But after flashing and connecting via mqtt I see that it tries ten times to synchronize and then gives up…so the logging message is never displayed:

Any idea why sntp isn’t working here?

thanks in advance

Hmm…

As soon I remove the font: and display: SNTP works then and goes beyond the point of setup() finished successfully…

Just not with a display…
