Is it my imagination or has the networking got worse since the "networking fix"?

[tienvx]

I tried to revert but:

• On macos 14 (arm): something wrong with github actions, I can't find solution for this error dyld[7202]: Library not loaded: /opt/homebrew/opt/xz/lib/liblzma.5.dylib
• On windows: The annoying error Script phpunit --no-coverage handling the test event returned with error code -1073741510 is still there + timeout error (I think something wrong with Github Actions)

so, no, I think something wrong with Github Actions itself. The fix does nothing. I will create PR to revert it.
