[Evergreen-general] Issues with Hatch and Chrome

Wed Dec 8 16:06:17 EST 2021

We have seen the same issue at random workstations. I don't understand all
of the details that Bob gave. I just know that on the affected
workstations, we have to refresh to get the Evergreen page to load. One
workstation is working normally after IT pushed through several updates but
we aren't sure that solved the problem or if it was a coincidence.
