Processing times can vary for many reasons, and people applying at the same time may typically receive responses around the same time, but it's far from unheard of that some applications take longer without any clear explanation.
There is always a standard reply of the timeline being 15-45 days but the 45th day is when my travel is planned.
You say you've been waiting for 25 days. That's comfortably within the range of processing times they consider normal. It's nearly three weeks away from the end of that range. There is no reason to believe your passport is "stuck".
As for how you can get further details on the status of your application: the embassy is likely the only place. You can contact them in whichever way you feel appropriate and request whatever updates they can give you. I know this isn't what you want to hear, but it's unlikely you will receive any additional information beyond the standard reply you have already received. The staff have more important things to do than thoroughly investigating the status of an application that's still three weeks away from exceeding the timeline they consider normal.
If you explain about your planned travel dates, it's possible somebody may be more inclined to look a little deeper and help make sure your application is processed before you intend to travel. The chance of that probably improves the closer you get to the travel dates.
