Do you mean that the job was queued? Has it run by now?
This mini-guide describes how the public servers queue and run jobs. Some of yours run, some of other people’s, more of yours, repeat until done. Using collections and workflows can speed this up dramatically.
Let us know how this turned out or if you are still waiting for some reason. The most common reason is that something went wrong with an upstream job. You might have to click into the collection to check if some jobs failed and some didn’t, and it might not be the tool immediately before, but a few steps earlier. You are welcome to share the job, too, for more specific feedback. How to share is in the banner of this forum, also here. → How to get faster help with your question
Hope this helps!
