I can't or it is too hard to capture for me. It is also hard to reproduce the issue. I will submit a screenshot and har file to this message.

Hi,
do you have any kind of VPN filter by protocol? QUIC is SSL over UDP so UDP443 is needed which can be blocked by firewalls.
Please rate and mark as an accepted solution if you have found any of the information provided useful.
