I am having an error using Flask applications. When I was using it on my work machine, it worked, but after transferring the files to another machine, the code gives a connection refused error.

Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Traceback

Please provide the full traceback for your exception in order to help us identify your issue.
While the last line of the error message tells us what kind of error you got,
the full traceback will tell us which line, and other critical information to solve your problem.
Please avoid screenshots so we can copy and paste parts of the message.

A full traceback could look like:

Traceback (most recent call last):
  File "my_file.py", line 5, in <module>
    add_three("6")
  File "my_file.py", line 2, in add_three
    a = num + 3
        ~~~~^~~
TypeError: can only concatenate str (not "int") to str

If the traceback is long, use our pastebin.

Does flask log anything?

Do you see anything in terminal?

If not, add some log messages to start with

What message do you see when running flask?

this message also appears on my job computer, but it works correctly

Is that from your local computer?

kind pumice

And what URL are you trying to access? Your screenshot doesn't show it

the same

My local PC has the same files, everything is identical.

Try chrome or another browser? Curious if you have a firewall setting or anything interfering.

kind pumice
#

i tried in chrome but the same thing :(

#

I added the firewall rule to allow port 5000. It's in Portuguese; if you don't understand something, I can translate.
