Battlefield 6 fails with error 0:51002S:57019S on

Battlefield 6 fails with error 0:51002S:57019S on Vodafone Egypt VDSL but works on Vodafone 5G. I captured both successful and failed sessions from the same PS5.

The failure occurs during the EA QoS UDP stage. On VDSL, the PS5 sends QoS2 probes from UDP port 7673 to 14 QoS endpoints. Every endpoint replies only to sequences 0 and 1; sequences 2–15 receive no response. On 5G, multiple endpoints successfully return all sequences 0–7, after which the client proceeds to BF6 services (bf6-mp-cgw.ops.dice.se, bf6-eventbridge.ops.dice.se, bf6-cdn.ops.dice.se).

Blaze/TLS connectivity itself succeeds on both connections. Please investigate whether the QoS service or network path is rejecting/dropping subsequent UDP QoS packets from Vodafone Egypt fixed broadband ranges.
