It's a bit of a modern management cliché to say "Don't bring problems! Bring me solutions!"

I think what that means is "Don't just complain! Think about improving things!"

It's good to think about improvement, but sometimes (if not often!) that improvement process starts by identifying problems.

In a "Kaizen" process in a team, I encourage people to bring problems forward even if they do NOT have a solution or "countermeasure" in mind. When somebody points out a problem, that can prompt discussion or brainstorming (with the manager and colleagues) about what solutions could be tested.

Here's an article from Harvard Business Review that delves into this same topic:

"Don't Bring Me Problems--Bring Me Solutions!"
