A Tour and Demo of Wave doesn't work (VPN/Proxy related)

[freegor]

Hi there,
I have installed the Wave 0.13.0 20210306054523 on my Mac OS Catalina.
I have installed Python 3.9.2.
After the installation the Wave is up, I see in bash:

2021/04/07 19:26:38 # ┌─────────────────────────┐
2021/04/07 19:26:38 # │ ┌ ┌ ┌──┐ ┌ ┌ ┌──┐ │ H2O Wave

and I can see the "WAVE LIVE" banner in the browser.
Once I start the Tour, everything looks good in the Terminal tab:

(venv) wave-0.13.0-darwin-amd64 user$ wave run --no-reload examples.tour
Welcome to the H2O Wave Interactive Tour!
Go to http://localhost:10101/tour
INFO: Started server process [23623]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

but in the browser on the /tour
I see the same blinking "WAVE LIVE" banner as well as on the /demo
Some ideas?

hi @freegor What messages do you see in your running wave server once you start the example tour?

This is an example of what you should expect to see once you have started the tour and then navigate to: http://localhost:10101/tour in a browser

@lo5 I see:
2021/04/09 20:23:50 # {"address":":10101","t":"listen","webroot":"/Users/user/wave/www"} 2021/04/09 20:25:46 * /demo {"d":[{"k":"hello","d":{"view":"markdown","box":"1 1 2 2","title":"Hello World!","content":"And now for something completely different!"}}]}
in console and same hello world bla bla text in the browser

[tkmaker]

@freegor That is promising. So the hello_world app does work as expected. It sounds like the tour.py app which uses port 10102 has an issue possible because of the port it runs on. Did you try the earlier suggestion to change that line in tour.py to see if a different port works ?
It is this line in the tour.py file :
_app_port = '10102'

But it looks like standalone apps are working fine. You can try running any of the examples similar to hello_world.py in the examples folder and navigate to /demo to see the app similar to what you did for hello_world

[freegor]

@tkmaker I tried to change the _app_port to a different value but have the same error.
bash_list-1.txt

[freegor]

@tkmaker If I run $ H2O_WAVE_ADDRESS=http://localhost:10101 python examples/tour.py, I see in the terminal:
Welcome to the H2O Wave Interactive Tour!
Go to http://localhost:10101/tour
But in the browser http://localhost:10101/tour I see only Wave Live logo

[freegor]

Finally after few days of experiments I have resolved it.
Seems the export no_proxy=127.0.0.0/8 doesn't work, changed it to export no_proxy=127.0.0.1 and everything works perfect now.
Thanks a lot gays all of you for trying help me, I appreciate it!
