"After doing some research, it appears the LoTW server changed their protocol options to strict checking to fix a vulnerability. However, that broke a variety of clients, including NetLogger. I had already decided I was going to do a 3.1.6 release to fix some bugs and make some other minor changes, but this problem will mean that I need to get it out sooner, although I may not be able to get a new one out for a week or two. So just hold off for now and upgrade when the new release comes out and you should be able to get the status updates. Meanwhile I believe the uploads still work, and you can check recent status on the LoTW website."
