Cannot create new ipython notebook or start jupyter
<p>Whenever I try to start Jupyter ipython notebook. I get the following error<a href="http://i.stack.imgur.com/TbhAr.png" rel="nofollow"><img src="http://i.stack.imgur.com/TbhAr.png" alt="enter image description here"></a></p>

<p>Sometimes, after restarting the system I am able to start the ipython notebook, I cannot create a notebook and it gives me the error saying Forbidden.</p>

<p>My command Prompt also says 0 active kernels</p>

Anyone else have this issue or know the answer to this problem</p>

<p>I used to have this issue too. It seems to be a bug because I restarted my PC and It would work normally again. It's been weeks I don't have this issue anymore and I didn't do anything to intentionally solve it.</p>

python ipython jupyter jupyter-notebook
