Hello everyone, I am trying to build slicer, but I am receiving the following error:

I have seen answers regarding connection issues, and I have disabled my firewall, but the problem persists. Has anyone been able to solve this issue? Thank you!

Could you provide the build output log in addition to just the error?

It has been a while, so I might not remember the fix for this one problem. Back then, I was building Slicer 4.x. I am currently building 5.X with VS2022, and I no longer have issues with it. Some of the previous problems were related to the git protocol as it was failing to download the packages, so it needs to be unchecked in CMake. Check your version of Qt to see if it matches what the building guide recommends.
