ConnectionError "Connection reset by peer"

See original GitHub issue

I’m getting the following error when running aqt install -O $QT_INSTALL_DIR 5.12.4 linux desktop. I’m getting this on multiple python versions (3.7 and 3.9), multiple machines, and from multiple different network locations.

Any help much appreciated.
