Hi, I have installed Jupyter and JupyterHub in Ubuntu and configured Apache as a proxy. But when I try to connect to http://localhost, I get the following error in the web browser:
*Proxy ErrorThe proxy server received an invalid response from an upstream server.The proxy server could not handle the requestReason: Error reading from remote server* I'm sure that JupyterHub is running. If I run it in degug mode ~# jupyterhub -f /etc/jupyterhub/jupyterhub_config.py --debug &>> jupyterhub.log ~# tail -f jupyter.log tail -f jupyterhub.log *12:59:08.662 [ConfigProxy] info: 200 GET /api/routes [I 2020-03-29 12:59:08.664 JupyterHub proxy:320] Checking routes[I 2020-03-29 12:59:08.664 JupyterHub proxy:400] Adding default route for Hub: / => http://127.0.0.1:8081[D 2020-03-29 12:59:08.665 JupyterHub proxy:766] Proxy: Fetching POST http://127.0.0.1:8001/api/routes/12:59:08.666 [ConfigProxy] info: 200 GET /api/routes 12:59:08.667 [ConfigProxy] info: Adding route / -> http://127.0.0.1:808112:59:08.667 [ConfigProxy] info: Route added / -> http://127.0.0.1:8081[I 2020-03-29 12:59:08.668 JupyterHub app:2631] JupyterHub is now running at http://127.0.0.1:8000[D 2020-03-29 12:59:08.669 JupyterHub app:2233] It took 0.617 seconds for the Hub to start12:59:08.669 [ConfigProxy] info: 201 POST /api/routes/* Then I try to connect to the server ~$ lynx http://localhost ang get the same error *The proxy server received an invalid response from an upstream server.The proxy server could not handle the request Reason: Error reading from remote serve*r and nothing is shown in the jupyterhub.log file. It seems that apache can't connect to jupyterhub. Any help would be appreciated Rafel Amer -- You received this message because you are subscribed to the Google Groups "Project Jupyter" group.
