Are you using Couenne through JuMP? If so, the [recommended way](https://jump.dev/JuMP.jl/stable/manual/solutions/#Recommended-workflow) to query solutions is to check that a primal solution indeed exists.

Normally, if a solver has found a feasible solution (even if it was not able to prove global optimality), it _should_ let you query it. In your case, you want to check that `primal_status(model) == FEASIBLE_POINT`.

If, for some reason, the solver log suggests that a feasible solution has been found, but the above check fails, there may be an issue in either Couenne itself or its wrapper.

Can you provide a reproducible example? (you can have a look [here](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/) for guidelines on how to do that)
