Who can help me solve this!!!

7 variables have not converged; Max Err/Tol is -0.42143E+02. What does this mean?? Can anyone perform acetic acid dehydration? Why is it so difficult to achieve convergence??? Please help me, experts!~~~~~~
It’s about putting an end to it~ Let’s describe it in more detail
No convergence; when using acetic acid for simulation, it is important to choose an appropriate property method – HOC property method
Acetic acid exhibits strong association; therefore, thermodynamic methods that incorporate HOC corrections, such as NRTL-HOC, should be used. The calculation process did not converge; one can increase the number of iterations, or check whether there is an issue with the specified value for the tower.
