Connected with commercial eNodeB, but TCP seems failed

Hi
We have modified v3.0.4 to connect our commercial eNodeB, we find that we can send and receive messages through Tencent Wechat, but we cannot open any web url or watch videos. Cannot find any error or warning in the log. Our DNS config is fine. We checked our UPF pcap, found that TCP Out-Of-Order seem occur. Does anyone have a clue?

It seems TCP MSS issue.
You can try this command on UPF to modify TCP MSS to 1400:

sudo iptables -A FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1400
