RB5009 upgrade check fails with connection time-out

I have a RB5009 on 7.2.3. acting as router to my fiber ISP. Wanted to upgrade it to 7.3.1 today but the update check times out?


routeros can access the internet, too:

[admin@MikroTik] > ping google.com
  SEQ HOST                                     SIZE TTL TIME       STATUS                                                       
    0 172.217.168.78                             56 112 2ms902us  
    1 172.217.168.78                             56 112 2ms865us  
    sent=2 received=2 packet-loss=0% min-rtt=2ms865us avg-rtt=2ms883us max-rtt=2ms902us

Are the servers down or am I missing something?

Must have been a server issue, I just tried again and it worked fine.
