Please read the first post of Please read: make it easier to help you.
If you can provide a simple example that reproduces the issue, it’ll be a lot easier to provide advice.
Try computing a feasible point via a different method (e.g., by hand), and then using the start keyword in @variable:
model = Model(with_optimizer(Ipopt.Optimizer))
@variable(model, x, start = 1.23
or set_start_value:
model = Model(with_optimizer(Ipopt.Optimizer))
@variable(model, x)
set_start_value(x, 1.23)
