Welcome @Ines_Leao
It does seem that the server had a few more queued jobs than usual around the time your wrote in but this appears to be resolved now.
See → How to see the UseGalaxy.eu job queue statistics
This section of the graphs is about the queued jobs. I see a really busy time earlier – this is represented by a peak in the graph corresponding to _DATA_FETCH_ jobs (which are from the Upload tool). Some of those 130+ jobs were probably yours!
The server was likely just busy. But please let us know if you are still having trouble and we can look into it more!
