Hi @FraserBell thank you for the feedback! I'm not totally sure what could be causing this but seems like this is a duplicate of https://github.com/spyder-ide/spyder-terminal/issues/330

Just in case, what happens if you try to access the server address with your browser?

I will move this to the spyder-terminal repo for the moment, but if you get more info in order to better understand this let us know!

mhechthz commented 1 year ago

I have the same problem. The terminal is accessible in browser but spyder fails to connect (Python 3.9, Python 3.10, spyder 5.3.3, spyder-terminal 1.2.2).

dalthviz commented 1 year ago

From the logs seems like the websocket is being closed. If the problem is related with the websocket handling maybe is related with the terminado version you have installed? What terminado version do you have installed @mhechthz @FraserBell ? What happens if you try to downgrade to terminado 0.13.3 ?

mhechthz commented 1 year ago

terminado==0.17.0 ... with terminado 0.13.3 it's the same problem. Terminal can be accessed via browser but not from Spyder.

What was the command to generate error log files? there is no documentation on this? ... found it: spyder --debug-info minimal

by the way: issue https://github.com/spyder-ide/spyder-terminal/issues/324 and https://github.com/spyder-ide/spyder-terminal/issues/203 are the same.

dalthviz commented 1 year ago

Thanks for the new info @mhechthz! I'm not sure what could be happening there sorry :/

The other piece of log that is interesting from the OP is the code 404 for the main.bundle.js - 2022-10-24 15:35:08 8afbf8f0.st-andrews.ac.uk tornado.access[12256] WARNING 404 GET /main.bundle.js (127.0.0.1) 258.44ms 🤔

Also, thanks for the feedback around all issue, will close them as superseded by this one :+1:

mhechthz commented 1 year ago

You forgot 203 ;)

a-ma72 commented 1 year ago

I had the same problem. Obviously, in my case it was due to the environment variable HTTP_PROXY that was set. After I remove the variable, the terminal in Spyder works again.
