I’m trying to install Unreal Engine 5.3.2 through the Epic Games Launcher.
Each time, the install hangs at 2% with this error message
We’re sorry. It looks like we’re having trouble connecting. We’ll continue to retry.
If I click on that error message I get sent to the Epic Games Help page for error IS-0005: Unable to connect, but working through the network connection troubleshooting steps did not help. I sent a support ticket through the Contact Us page as instructed by those troubleshooting steps, but my issue was immediately closed and I was told to post here instead.
If I look in the EpicGamesLauncher.log, I see many sections that show HTTP timeouts

After running through all of the network troubleshooting steps without any luck, I tried to select a different version of Unreal Engine instead, and version 5.2.1 downloaded and installed successfully without any issues.
