Since yesterday we are having issues with loading our tilesets via ion source.
We are hosting our unreal apps on a pixelstream service. Since yesterday all of the apps dont show the tilesets anymore. We cant reproduce this localy or in unreal itself. What we have noticed is that it does work when loading the tilesets via an url (tested with google tilesets) instead of the ion id.
Since we use a lot of very big tilesets we cant include the tilesets directly in the build to load them via url.
We tryed reaching out to the pixelstream service (Arcware) and they were aware of the problem, since other customers were facing it aswell. But they told us that they didnt change anything.
We assume it could be because certain ip adresses or requests get blocked. Were there any chances from your end?
If this is to little information, please let me know and i can follow up with a detailed description of our setup. Also if there are any informations regaring the pixelstream service that are needed to resolve this.
Hi @HEGIAS, this is an issue we’ve been hearing from other customers as well today. Our AWS certificates were renewed this week, and we suspect this is the issue. Can you try the following to see if it helps?
Clearing the DNS cache on the machine.
Delete the cesium-request-cache.sqlite file, which should be located in the Engine directory of the packaged app.
Restarting the machine that Cesium for Unreal is running on after performing the previous two steps.
Hi azrogers,
I also created a post about this issue in a packaged game. I tried the steps above and that did not fix the issue for me in a packaged game.
Clearing DNS isn’t possible(?) because I use Arcware to rent VM’s for Pixel Streaming.
I’ve deleted cesium-request-cache.sqlite, reuploaded the package, and tiles still don’t stream.
Restarting the machine shouldn’t(?) matter, as the VM’s startup on request.
I’m not sure how installing the Starfield Services Root Certificate Authority from AWS will work, since I rent out VM’s from Arcware, as recommended HERE
My project is packaged to Windows. This issue arrived within the last month. All of my previously uploaded and working projects are broken, failing to load your gorgeous tile sets
I can provide a link to the Arcware stream and/or .zip package directly to a Cesium Team member, if requested.
We are also in contact with arcware to find a solution. I will update here aswell as soon as we have found something that solves the problem or some meaningful next steps are defined.
@CoulterHeiberger would you mind sharing Arcware’s message from their Discord? I’m curious what they’re saying about it, and am not on their Discord to check myself.
