The Output screen gets this error "There was an error connecting to the server"

I have tried to refresh the output page, but it still gets that error, even I have tried another browser like Chrome.

Hi there @truongkhoawastaken , have you tried forking the repl, and see if the forked version works?

Hey @truongkhoawastaken welcome to the forums!

Could you provide a picture on your end of what it looks like, and a link to your Repl so we can look into it further?

Thanks for replying? When I run the Flask app on Python on with the file name, then the output can’t used.

But I’m the owner of my Repl.

@truongkhoawastaken have you followed the steps it suggested?

Have tried, it only works when I type the neofetch command in the shell when I have closed the Output page.

Check the console and make sure your code has no errors that crash it.

If there are none and the output does not show, ensure the domain ** is allowed on your network.

If all fails, please send me the link to your Repl and I’d be happy to take a look.

Here’s the link for the Flask

Your VNC output seems to be displaying fine. Are you still experiencing this issue?

Yeah, still fine, also I try the experience with Firefox on that. :+1:

Hello truongkhoaui,

I have the same issue like you. Did come over on it? Is it working for you? If yes could you please help me to solve the issue as well?
Many thanks in advance!

The first thing, you can take the Output screen back by typing the neofetch command in the shell, if it doesn’t available in Nix, add it then execute the command, after that click Try again in the output. Remember if you are running Flask container you mustn’t use the Output screen.

I found this error only ocurd to me when I closed and then reopened the output tab.
