Smoothwall not allowing Replits to work

[kennysarmy]

Just getting "There was an error connecting to the server" in the Output pane of Replit.

 

Nothing obvious in the Smoothwall logs.

Bypassing Smoothwall it works OK.

 

Following are all in a category which is "Not Inspected" & "Do Not Filter"

 

eval2.janeway.platform.replit.com

production-ai-chat.replit.com

replit.co

replit.com

replit.com/~

vscode-cdn.net

 

 

Must be missing something, but can't work out what :/

 

Smoothwall ticket opened, but they can take a while so posting here in case anyone has the answer.

We've had a bit of an issue with this. Even going to the extent of opening Inspect element and going through the Console option to find some urls.

 

Some we found were:

 

eval.global.replit.com

gp-v2.replit.com

sp.replit.com

 

Hope that may help

I wish I could help but we gave up on this. It was the VNC port 5900 connection in that right hand side frame that was the issue, and after a few weeks of trying our computing department decided to go in another direction.

Added to my allow category in Smoothwall but sadly the connection still cannot be made

I'm not seeing anything relating to VNC.

It was a websocket failure on port 5900, the vnc port, for programs that had a graphical output. Pygame stuff was the main culprit.

 

Websocket connection to '994.81ba10eeeb296091.js:1 WebSocket connection to 'wss://6641250c-c512-48f0-9305-4b77d245c086-00-1vcw7bgv8on82.spock.replit.dev:5900/' failed

I got it working yesterday putting a firewall rule in place to allow TCP traffic out on port 5900 but it's stopped working today. Destination is still the same. I haven't tried adding a UDP rule to allow port 5900. I'll try that now. Edited May 23, 2024 by bknaggs
UDP not UNC

[bknaggs]

Adding a UDP rule doesn't make a difference. Bringing up the Dev tools in Edge gives me

This is going through Smoothwall cloud filter in our case and bypassing the local box.

Did this a while back but ended up moving to firewalledreplit.com https://docs.replit.com/additional-resources/firewalled-replit and put these in "Do not inspect"

 

*.firewalledreplit.com

*.firewalledreplit.co

*.cdn.replit.com

Smoothwall first line couldn't help, so waiting for second line to make contact.

[tom_newton]

Looks like a tough one - I will raise it with our team.

[kennysarmy]

Second line remoted in.

 

Category list amended to:

 

js.stripe.com

repl.co

replit.co

replit.com

replit.dev

vscode-cdn.net

 

port 5900 is added to web proxy settings > Additional web port settings.

 

 

 

Strangely the test Replit was not even connecting for the second line engineer on his own PC, so not sure if we actually fixed anything or if the REPLIT site was having issues which co-incidentally were resolved during our call !

 

 

Asked Head of Computing to run more tests.

 

 

This was test Replit

 

from tkinter import *

 

app = Tk()

 

 

app.mainloop()

 

 

The "webview" in a filter test still blocks access to sites students should not be able to access.

Nothing to do with the original problem, but be aware that LOTS of web proxies are hosted on replit.
