Grid connection refused exceptions.

[PadineanuCosmin]

Using the latest Chrome 80 image(with Zalenium) grid connections are refused. After this occurs the nodes disconnect from the hub and the hub freezes most of the time.

With the Chrome 79.0.3 image this doesn't occur.

Errors are the standard Selenium connection refused ones:
