I have been using Jupyter Notebook successfully for a long time, but today I have encountered a strange problem. Running on windows 10, if I type
jupyter notebook in a command prompt then I see the usual text and startup appears successful.
However, when I try to open jupyter in a browser tab I cannot connect, the page remains blank with the little ‘loading’ icon on the browser tab spining indefinitely.
I have tried opening:
http://127.0.0.1:8888 and have also tried opening via
In the latter case I see the text:
This page should redirect you to Jupyter Notebook. If it doesn't, click here to go to Jupyter.
But jupyter never loads.
I have not changed any system settings since I last ran jupyter successfully. Furthermore, I have tried three browsers (Chrome, Edge, Firefox) and have the same problem on three separate PCs, two of which are Win 10 Enterprise and one is Win 10 Home. I have tried opening ports on the firewall but that doesn’t help. Confusingly, I can connect to a remote notebook fine (via ssh), it’s only loading a local copy of jupyter that’s problematic.
Any ideas what the problem could be? i’ve run out of ideas.
