hello boss
Can this error be solved?
connection does not allow setting of send buffer size. Not a *net.UDPConn?. See https://github.com/quic-go/quic-go/wiki/UDP-Buffer-Sizes for details.

Of course, this was ai's answer

Answer
The error message "connection doesn't allow setting of send buffer size" in v2rayNG software means that your connection is not of the type and cannot set the send buffer size. To fix this problem, you can increase the size of UDP buffers using the following commands in Linux:net.UDPConn
bash
sudo sysctl -w net.core.rmem_max=2500000
sudo sysctl -w net.core.wmem_max=2500000

These changes will help you avoid this error. Also, make sure the proxy settings and UDP ports are configured correctly

What config are you using? AFAIK it is already *net.UDPConn unless you are using dialerProxy. And BTW this does not affect anything and you can just ignore it.

Hi
SplitHTTP h3 cdn
This was an error that was shown in the Report error section of v2rayNG

Full config? AndroidLibXrayLite should have already provided correct *net.UDPConn. If you don't use dialerProxy this should not happen. If you use dialerProxy I don't think this can be fixed.

If I'm not mistaken, xhttp or splithttp uses dialerproxy
For example
XTLS/Xray-core#3570

Next, you have come here, if possible, take a look at AndroidLibXrayLite and v2rayNG, if something is necessary, commit pr😅🙏

dialerProxy is not a must for xhttp. So this is because your final config contains dialerProxy, right? I came here just to check if my PR 2dust/AndroidLibXrayLite@43cde7a is causing this. Nothing need to be fixed if you are using dialerProxy. Just ignore it and continue.

The boss should also comment on your former PR
