Hello, everyone.

I'm having that annoying E3 (unable to connect to GOG servers) problem with almost evey "big" game which i'm trying to install though Galaxy 2.0. It seems that only games whose size is bigger than 10 GB are affected - for example, "Batman Arkham City", "SOMA", "Mad Max", e.t.c. When i tried to download and install NWN Enhanced Edition, it was successful, as well as "Shadowman Remastered" installation.

I followed the instruction in one of problem-related threads and made clean installation of GOG Galaxy 2.0, but it helped me only for several days, and then that E3 again. It began over a month ago, and i can't do anything about it ever since without clean installation of Galaxy every time when i want to download something with it again.

Galaxy's and GOG's folders are white-listed for my antivirus, and all web access allowed for Galaxy. Manual downloads from GOG works fine.

Am i the only one having this problem? Help me to lift off my paranoia.

Thanks.

UPD: Okay, got this one fixed. Somehow my not-that-smart firewall has been activated by itself after antivirus and Galaxy re-installation thus blocking all "unreliable" connections for several programs, By excluding GOG Galaxy's .exe files from black-list i've been able to resolve that problem with E3 error.

I am having this very issue and my antivirus is turned OFF. I downloaded the GOG Galaxy App from their website using Chrome and had ZERO ISSUES doing so, as well as logging in without issues.

Being an Amazon Prime member, they offered Fallout 2 (last week it was the 1st one and I'm kicking myself for not getting it too), and so I looked up the specs and saw my Windows 11 Intel UHD 605 could run it and it could, so I wanted to play it as I used to have a modded version of Wastelands, New Vegas and one other all in the same game, and had a TON of fun. But with this issue happening, I have no idea how to fix it as I have NEVER had this issue before on my Windows 10 even with my antivirus ON!!!

Support is useless as I don't know or understand what they really want from me to send with my question, and it seems like there's really no true solution if this has been ongoing for YEARS and they have yet to find a workaround this E3 error because I would really like to play this game and having to deal with being told that it can't connect to GOG servers despite being LOGGED INTO THEM and the install getting to 5% before failing is just REALLY FRUSTRATING!!! This is on a FRESH install of the GOG Galaxy App too, as it's NEVER been on this laptop till now.


And this is GOG Galaxy 2.0.73 the issue is STILL PERSISTENT with.

getting the same issue too, just got a the free game "Book of Demons" and it won't install.

I'm getting this issue as well. Just purchased Star Trek Voyager Elite Force and I cannot download it through the Galaxy client. Likewise, I cannot download it from the website with the offline installers. I get kicked to an error page that has different headers (JSON, Raw Data, Headers) and it says "invalid license".

EDIT: Took some time, but looks like the error sorted itself and was able to download the game.

I just started getting this message but only with Cyberpunk. It's stuck at 62% Other games install fine. I just bought Phantom Liberty so I'm wondering if that isn't related?

I'm getting this with Kenshi as Galaxy says it's only 297 MB to install, which is incorrect.

Edit, seems to offline installer for Kenshi has updated, but is the incorrect size as well.

Was really helpful! thanks still works

Hey thanks, this just worked for me. I tried a lot of other troubleshooting suggestions but none of them helped. Clicking both these links caused GoG Galaxy to retry the download and it is working now.

Doesn't help with Metro:Exodus. The installation is stuck at 92% and everytime I retry it shows me the E3 error

Hallo,
Dragon Age stucks at 92 percent, refreshing didnt help
