How to sole the problem of "ConnectionRefusedError: [Errno 111] Connection refused"

[yibingchen2023]

When I run the code, I can't connect the url " /records/14445620/files/release_v1.5.0.zip?download=1". How to solve this problem? Can I download the corresponding files using other ways?

[FabianIsensee]

Hey,
I just verified that this works. Can you please try again and post the error message?
Best,
Fabian

Thanks, and the error message is as follows (I am in China):

[yibingchen2023]

Thank you very much. I have good news for you. When I used proxy software with the foreign servers and ran the coding again, it worked without any errors!

[FabianIsensee]

Great! Happy it works now!
