Same here with probe 31884. Interestingly I have a Fritzbox at home as well. I discovered no problems with the network at home, the services worked as expected and as a test I changed the DNS from the provider to 8.8.8.8 and 8.8.4.4. Which did not helped.
As a last step, I transferred the probe temporarily to the company network and have the same issue. Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum
