websocket can't connect -- main menu #848

danvinci · 2021-01-16T00:10:37Z

Hi!

First of all, thanks for creating Pluto!

Pluto 0.12.18, macOS 11.1
I'm running into the following issue very frequently:

start Julia and Pluto
open a new or existing notebook
going back to the 'home' clicking on the logo
Pluto becomes unresponsive, including the notebook path bar

Restarting Julia has a 50/50 chance of fixing the problem, but also of opening Pluto directly in this 'always loading' state.

Any suggestions on how to go and gather extra information on what's going on?
In the REPL I don't get any messages.

Which browser?

danvinci · 2021-01-16T14:50:15Z

Firefox 85.0b5 Dev Edition

(although once stuck, it's seen regardless of browser, also tried in Chrome).

Also, another way to replicate the issue, at least on my installation:

open a notebook
click on the 'Statistics' link in the footer
go back in navigation
I end up in an empty notebook and Pluto looks disconnected

So, I'm again at the point described above and I have to restart Julia & Pluto a few times to get it to work.
No updates in the REPL as this happens.

danvinci · 2021-01-17T16:07:23Z

I tried to delete everything in the ./julia folder and re-install relevant packages, the problem still persists.
I managed to create a new notebook and run commands things like ''1+1'' and everything was fine until I tried to install Plots and run into #228 (REPL output below).
Also, the only way I can open notebooks is to copy/paste directly their path, as the bar is not working (no autocomplete).

A strange thing I've noticed is that in Statistics I see this:

Things that jump to mind:

"versionPluto": "unkown" (I'm using v 0.12.18)
"screenWidthApprox": 1200 (I have a 2-screens setup and they're both 1920x1080+)

I tried to open a sample notebook from another tab but nothing happens, I only get to see ''Reconnecting'' on the top right.

It's been a few days that I can't use Pluto:
even if I manage to create a new notebook it won't open again next time, or if it does I run into #228.

Any suggestions on what I can do?

Here the REPL output of when I interrupted the cell installing Plots as it was taking 2+ mins (sent the stop signal a few times and had partial executions in between):

This is the incriminated notebook: https://gist.github.com/danvinci/2c97c432b1d224007f7449780a9e96b5

fonsp · 2021-01-17T16:39:56Z

Can you follow these steps (you have done some already): #553 (comment)

The issue is that the WebSocket connection fails, so let's focus on this. Statistics, opening notebooks and cell interruption are unrelated.

In the main menu screen, with a broken connection (first screenshot), try the following, and report what worked:

Refresh the page
"Clear cache and refresh" the page
Open the main menu in a different browser
Run Pluto on a different port: Pluto.run(port=2345)

danvinci · 2021-01-17T18:32:37Z

Ok!

So:

Refresh doesn't work
Clear cache and refresh doesn't work

When switching to another browser, same port:

it works only if the startup was successful (loaded previous sessions, file path bar is responsive), and I switch from FF to Chrome
behavior is not 'predictable' and I'm only able to run the first few cells of a notebook (installing packages) until I run into long-running cell problems

When using another port:

if startup is not successful in FF (stuck at loading) in Chrome I get this:

(no previous sessions loaded - probably makes sense (?))

but, compared to FF, the file path bar is responsive and I can locate/open/run notebooks
in FF, even copy/pasting the URL in the bar, it results in the editor being opened with the notebook never being loaded

Hope it helps!

(using Chrome on another port is working so far)

fonsp · 2021-01-17T21:53:45Z

Thanks! The most important thing is that you share the output of the browser's development console: #553 (comment)

danvinci · 2021-01-18T00:55:07Z

Attaching the FF console export!

console-export-2021-1-18_1-54-27.txt

fonsp · 2021-01-18T22:21:43Z

It looks like you shared something internal in Firefox, can you instead share the output of the Web Console? https://developer.mozilla.org/en-US/docs/Tools/Web_Console

fonsp · 2021-01-18T22:23:02Z

Also try disabling ad-blocking extensions for the Pluto address (localhost:1234)

danvinci · 2021-01-19T12:41:51Z

Ok!

I've copy/pasted the output of Browser Console instead of Web Console.
Here the output of the FF Web Console.

In this case, Pluto is working in Chrome and I've tried opening it from Firefox (with the proper link including the secret).
I've also disabled uBlock on the domain and refreshed the page before copying any web console output.

fonsp · 2021-01-19T13:36:10Z

Is there any output in the julia console when you do this? When sharing this output, do not open notebooks, use the file picker, etc, but just start Pluto, go to the address in firefox and get the console output.

danvinci · 2021-01-19T13:41:56Z

Nope, nothing in the REPL.

The output above is from the Pluto main screen, only tried to use the picker.
