Hi my VPN clients started to comply more and more about QUIC protocol connection issues (ERR_SOCKET_NOT_CONNECTED or ERR_QUIC_PROTOCOL_ERROR) when connected to my AWS hosted ASAv (software version 9.18(2)). Please assist.

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.

HTH,
