FIXED: Opensource installations currently facing problems

Update 1.8.2023: The issues have now been resolved.

We are currently facing issues with opensource installations of Qt. Root cause is a bug in the latest installer. We are working on fixing the issue and there are a few ways to work around it.

Newest installer 4.6.0 is facing problems with open-source installations. Reason for that is that online installer does not use mirrors correctly which is causing extra traffic to our master download server. At the moment there are many downloads because of the new Qt Creator 11 and Qt 6.5.2 releases and therefore installations for open source users are really slow.

We are working on fixing the bug in the installer and improving the amount of mirrors with the latest release content. In addition, we have asked our service provider to increase the bandwidth of the master download server.  This problem is not concerning any commercial Qt users.
