Lessons do not complete

After answering the last question of a lesson and pressing on "Continue" nothing happens. I see the loading indicator turning but the lesson summary won't show. After a while the home page opens where I can see, that i didn't get any points. I tried this with different browsers and different lessons.

Look like the PUT request at the end fails:

I've been having this problem as well, on multiple computers on multiple networks, not sure how to fix it; I'm not using a proxy.

I found the problem: Hotspot Shied Elite seems use a local proxy at 127.0.0.1:8555 that causes the problem. When deactivating this proxy everthing works fine again.

It sounds like the proxy is misbehaving. We changed the PUT URL to be unique per session, but even with this change your proxy is interfering. Thanks for letting us know about your proxy and that it caused a problem for you!

I am also having this problem, but only about 50% of the time. I have tried different computers and browsers, and I don't use a proxy.
