This is the type of error I am getting after running this command
jupyter notebook --allow-root

this is the command that really helped me

I have a linux server. On that I have installed Miniconda3 and other python packages along with Jupyter.
Now I want to run the notebook on the server and open in my browser.
For that, after installation of all packages, I do:
user#remoteip:$ jupyter notebook --no-browser --port=8890
Now I am copying the server IP address along with port to open it in my local browser.
http://remoteip:8890
However it doesn't open up anything.
I then followed all suggestions given in this SO answer by adding the required statements in the configuration file on the remote server anaconda and even local anaconda jupyter config file.
But it doesn't help at all.
After that I had to port forwarding as below in my local terminal:
user#localhost: ssh -N -f -L localhost:8890:localhost:8890 user#remoteip
And after that when I open
localhost:8890
now it opens up the notebook requiring the token to be entered and then it works.
My question is that do we need to do port forwarding everytime for us to open a notebook on remote server? One of my colleague said he didn't do any port forwarding and after first step itself, he was able to open the notebook with by typing
http://remoteip:8890
So I am not sure we need to do port forwarding for us to open the server jupyter notebook to open in browser or we can directly open the notebook with remoteip address?
Edit:
As per Alex's suggestion below, ran the following command after logging into dev server.
(ds_env) user#devvm1049:~$ jupyter notebook --no-mathjax --no-browser --ip 0.0.0.0 --port 8890
[I 23:49:56.032 NotebookApp] Serving notebooks from local directory: /home/user

[I 23:49:56.032 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
Copied the above link to both chrome and Safari but it didn't open anything.
I have already done the above suggestions in this post. The only thing that has worked until now is doing Port tunneling but that is 3 steps everytime one has to open the jupyter on remote server.
Is this can be some port blocking issue? I tried pinging the remote server on laptop and it didn't give me any ping.
If you specify the --ip option when starting the server you can allow remote connection without port forwarding.
jupyter notebook --no-mathjax --no-browser --ip 0.0.0.0 --port 8890
# The --no-mathjax improves loading over slow connections
This is not recommended, though. See running a public jupyter notebook server. If you do this, I strongly recommend that you set a password, as described in that link.
I get an error when I use jupyter-notebook in vs-code with the newest python extension. After creating a new blank jyupter notebook with easy command every time I failed to launch jyupyter server. The error hint is 'Error: The Jupyter notebook server failed to launch in time [I 23:22:42.012 NotebookApp] The port 8888 is already in use, trying another port.' or 'jupyter notebook server failed to launch in time' and nothing displayed in the debug console.
What should I do?
I have a problem with connecting to jupyter that I run on remote computer. I have configured jupyter with ssl as in the following doc:
https://jupyter-notebook.readthedocs.io/en/latest/public_server.html#hashed-pw
Then I run jupyter on remote machine with command: jupyter notebook as in tutorial.
When its running I make a tunnel in another terminal by running a command:
ssh -N -f -L 8889:127.0.0.1:8881 user_name#hostname.com
Of course the jupyter is running on port 8881. When I open the browser on my local computer and try to open page:
localhost:8889
I got an error that connection was reset, and in command line the ssh returns the following error:
channel 2: open failed: connect failed: Connection refused
Can anyone help me? I was looking for an answer for whole day and still can't fix it.
The problem is, that in my case jupyter is running on localhost. At my server remote server I have no access to remote localhost, so the solution was quite easy - I run jupyter on specified ip = 0.0.0.0
jupyter notebook --no-browser --port=8881 --ip=0.0.0.0
1) I tried to open Jupyter Notebook in Anaconda prompt.
Ananconda Prompt:
(C:\Users\sankarreddy\Anaconda3) C:\Users\sankarreddy>jupyter notebook

Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
http://localhost:8888/?token=fb39c20421e31cc66fddfd4fc00c7f64b8003bc53b83f461
2) My default browser is Google chrome and every time when I try to open the Jupyter notebook, the following is the result.
Result in the Browser(Google Chrome):
ERROR: Gateway Timeout

3) I interrupted the process using 'Ctrl+C'.. it displays as follows.
[I 19:43:23.364 NotebookApp] Interrupted...
[I 19:43:23.365 NotebookApp] Shutting down kernels
I have googled about this issue, but had very little help which is of no use.
It seems like you're trying to open Jupyter Notebook in port 8888 as stated by the error message While trying to retrieve the URL http://localhost:8888/tree?token=4f3786890eceb91493af9bd6f4b07ae1ac6888c6172bbfca
But, when running Jupyter Notebook, there was an error message stating something else is running in port 8888 and it started the server in the next available port, which is 8889: [I 19:26:39.239 NotebookApp] The Jupyter Notebook is running at: http://localhos t:8889/?token=86664b50ba28f3bd3431554bc84d60d8bf4f3bf4209a4ecf
I'm not sure how to identify what is running on 8888, but you should definitely access your Jupyter Notebook on localhost:8889 .
I've been tryin to run some simple code in IPython notebook but i keep getting this error:
"A WebSocket connection could not be established. You will NOT be able to run code. Check your network connection or notebook server configuration."
There were no problems during the install and there are no error messeges when i load the notebook.
I'm thinking maybe it has something to do with the fact im running my local server on xamp?
Doed anyone have a clue how to solve this?
I would be very greatfull.
Edit: I'm loading my notebook using the command 'ipython notebook' in the command prompet the output is:
[NotebookApp]"Using existing profile dir: c:\users\Nimrod\.ipython\profile_default
[NotebookApp]using MathJax from CDN: http://cdn.mathjax.org/mathjax/latest/mathjax.js

Thanks a lot.
Okay, by default ipython notebook launches standalone using the tornado http server running on local port 8888.
Try typing localhost:8888 into your browser.
If you want to customize it to run on a different port use:
ipython notebook --port=<NEW PORT>
If you'd also like to allow connections from remote machines do:
ipython notebook --ip=0.0.0.0 --port=<NEW PORT>
