While solving a LP, I ran into the following error. Below some snapshot from the message window.

Warning: Model status 13: Error no solution, Solver status 10: Error: Solver failure.
I am wondering if dual simplex solved the model, why there is error no solution?
Any ideas to troubleshoot this error?
With kind regards and Merry Christmas,
