Describe the bug Glances web server fails to start on windows 11.

I have already tried the mentioned solution from here: #3101

FWIW the opposite of that solution has been working for me. I.e. glances installs netifaces2 but actually only works with netifaces:

pip uninstall netifaces2
pip install netifaces

But I would love to not have to do that, +1 :)

I tried it the other way around, but that didn’t work for me either. :(

Can i do anything to help with the test or with the investigation of this?

I am having the same exact issue too... Only the webserver version is not working. Glances in terminal works fine.

pip uninstall netifaces2 pip install netifaces-plus This works for me.

pip uninstall netifaces2 pip install netifaces-plus This works for me.

This works

Same problem still occurs in latest version. I have installed everything 'fresh' (all python packages), I updated all and spent hours to solve cause of error.

Python 3.13.3 pip 25.1.1 Glances version: 4.3.1 Glances API version: 4 PsUtil version: 7.0.1

Exactly same error message as one above.

After saw this issue, I uninstalled netifaces2, installed netifaces and then problem solved.

This issue is stale because it has been open for 3 months with no activity.

pip uninstall netifaces2 pip install netifaces-plus

This works for me.
