Unreal Engine and AWS

Hello,

a few days ago I installed UE5.1 and tried to run a copy of my project made on UE 4.26.
Of course for obvious reasons (slow level loading, 0 FPS, a number of crashes, extreme RAM usage, etc.), I continued my work with the old Ue4.26.2 and noticed something that surprised me a lot:
Every attempt to import objects started with a long wait… (the import tab appears after 2-5 minutes, then another 3-5 minutes of waiting, and only then does the dialog box appear asking me what and how I will import, from there on things went relatively quickly)
Before installing UE5.1 I didn’t have these problems.
Also in the output log I got strange warnings about not being able to connect to a number of IP addresses outside my network and system, when I checked them they turned out to be addresses in AWS - Amazon Virtual Server (this happened when, due to a suspected leak, I blocked all outgoing connections to my computer and specifically on the ue engine)
I want to ask (because I’m interested, and probably not only me, but the whole community using Unreal Engine):
Why does the editor even attempt connections to these IP addresses and what function is performed after a “successful” connection?

If anyone could enlighten us on this matter, we would all be very grateful!

Hi, I would check for unintended plugins being activate.
You could try going to Edit > Plugins (in the UE Editor), and then searching for amazon or aws to see if you have a plugin activated. If yes, then just uncheck and restart.

Thanks for the reply!
I have never installed such plugins in this project and i’ve just checked again and there are still non :).

A solution to this issue:
I recommend UE4 users to not use live link plugins (especially those distributed via github and widely advertised on YouTube).
It took me a long time to clean the entire project of links and references created after installing such a plugin, which was literally scattered all over the project and in the background trying to make connections to remote servers.
I have no idea what the purpose of those links was but I don’t like people poking around, so I took the time and blocked all outgoing links (“official” and unofficial) and cleaned all possible plugins, which solved the problem at this point.
