Let us say I have finished discovering a set of 12 games and want to discover another set of 12 games. Then I have to click on
Start another Queue. At this point, either the process goes fine, or I encounter the following error:
There was a problem saving your preferences. Please try again later.
When I click
OK and then reload the page, after around 6 seconds, another error message appears:
An error was encountered while processing your request: Failed to load queue
Here is a video recorded by a Steam user of the process described above:
The error message
Failed to load queue can also appear as soon as I click on
Click here to begin exploring your queue. When this is going to happen, there is no background game banners visible behind the brown rubber band.
It might be relevant to mention that there exist preferences for Steam Discovery Queue at this webpage:
After I refresh the Steam Discovery page, or go to a page on the Steam store, or visit a profile on Steam community, the issue sometimes disappears. Sometimes, if I manage to modify my preferences for Steam Discovery, the error disappears. Sometimes, I just give up and the issue disappears when I try again a few hours later.
I believe this error mostly happens to people who have already discovered thousands of games. It seems the error also occurs for some users during major sales, and could be linked to Steam network being overloaded.
