Qatar will do anything that you make your next flight. I assume that your tight connection is the result of a flight booked with Qatar and the connection time was 2 hours in the booking.

if so relax. When my wife and I travelled to the Maldives our inbound plane was delayed by so much that we had t-10 minutes on arrival.

We noted this to the cabin crew and of course many more people had the same destination. Once we were off the plane a Qatar employee was waiting for us with a buggy and hushed us to the gate of the outbound flight.

The plane was delayed by a few minutes but all went smoothly. Overall 2 hours should be fine. And in DOH you’ve got a lot of personnel who can help you if need be.
