[2023] GW2 Installer stops download randomly and for good [Merged]

Sorry for the trouble. We have some kind of network congestion error that causes some of the 670,000 files we download to return an error that stops the download. The bad file gets cached in our Content Delivery Network. We're running downloads on our own and finding these files and flushing them from the cache. As best as I can tell it's much more reliable today than yesterday, which was pretty tough, but you could run into one of these files anytime. We continue to look for the root cause so we can fix it permanently.

We believe we've found (and fixed) the root cause of the game download issue. We have identified the mechanism that was causing corrupt files to be stored in our Content Delivery Network (CDN). That *should* mean that this problem is resolved. We're keeping an eye on it, but we think we're in the clear. Some of the edge servers for our CDN may have their own unique errors—we’ll only be able to fix those after we learn about them. For most players, there is no action to take for this to work—next time you open the launcher and start downloading files, it should work. For some players who modified their hosts file to work around the problem, our fix will have made it impossible to log in. This should only apply to players who specifically opened and modified their %windir%\system32\drivers\etc\hosts file (so if that sounds unfamiliar to you, you probably didn't do it). If you did modify your hosts file, you'll need to undo that change in order to continue logging in and playing the game. Once you've backed out any change you made, you should be able to download and play as expected. If, after modifying your hosts file to remove the change, you still get an error, we'd like to ask that you run the game with the "-log" argument to get a log for CS and our engineers to review. To do so: Open your Guild Wars 2 folder. Right-click on GW2.exe and select Create Shortcut. Right-click on GW2.exe - Shortcut and select Rename. Rename the shortcut to Guild Wars 2 Logging. Right-click on Guild Wars 2 Logging and select Properties. Locate the Target line and add -log after the existing text. Your target line should now look something like this: C:\Games\Guild Wars 2\GW2.exe -log Click OK to save your changes. Run the launcher, experience the download problem, and close the launcher again. Open an Explorer window. In the nav bar, type %appdata% and press Enter. You will now be in the AppData\Roaming folder Open the Guild Wars 2 folder. Find the gw2.log text document. ...then you'll want to submit a Tech Support ticket with everything you know about the problem. Within a few minutes, you'll receive an automated response email from [email protected] via zendesk.com; you can reply to that with your log file. Again, these steps are for folks who modified their hosts client and are still getting an error. We appreciate everyone's patience as we dug into this and got a fix in place.

Hello all - The source of our problem was people skipping around the CloudFront cache. We blocked a number of those sources yesterday and just within the last hour another large group. Just now I fully patched the game from Dublin (via a VM) and didn't have any errors. In spite of that, there are 240 edge nodes around the world, and the one you connect to might still have some bad files, so please if you get blocked, send your gw2.log file to our CS people so we can stomp out the bad files. Anytime we invalidate a file it gets invalidated for everyone. (The terminology is odd - invalidating a bad file in this case is a good thing. The reason we don't invalidate all 670,000 files is that it would stress out our origins.) Thanks.
