nRF Connect SDK can not download from Toolchain Manager. Too slow.

[strv]

I'm new to developing nRF devices. This is the first time to set up SDK.

I installed Toolchain Manager v1.2.6 to install SDK, but it is too slow and falls into error.
It takes over 3 hours after clicking the `Install` button to become an error.

Error message is

Error: Error: Failed to download toolchain bundle Caused by: 0: request or response body error: error reading a body from connection: end of file before message length reached 1: error reading a body from connection: end of file before message length reached 2: end of file before message length reached

Is it possible to change the download source? Is there any other method to solve this issue?

I'm currently trying to download v3.1.1 SDK and has also taken well over three hours (Via Visual Studio Code). 
I tried to manually download the SDK from the website and cancelled after 2hrs when it had only downloaded 53Mb... 

Definitely something up with the upload speed (connection or throttling) from the file server hosting the SDK's based on everyone's messages and from googling to see many other people having these issues.

Hi Tristan,

I downloaded v3.1.1 yesterday from home network using VSC and it downloaded SDK and toolchain within 10 minutes. Can you please give me more details on your work station OS version and VSC version? I did not hear any speed issues in downloading it yet, unless the server for this was slow exactly at the time of your download.

Hi Susheel Nuguru , 

I tried a number of methods over 3 different days all with extremely slow results, and based on the number of forum posts and similar issues other people are experiencing this is not isolated to me. 

Are you possibly on a nordic VPN and/or connected within their network - thus not experiencing this issue? 

I am using an Macbook Pro - M3 chip. 
I finally managed to get it to work with the following (took ~9hrs to download): `caffeinate -di nrfutil --log-level=debug sdk-manager install v3.1.1`. (caffeinate to ensure no sleeping and retries). 

All other website speeds for everything else was super quick and speed tests showed >200Mbps (both speed test sites and the built in speed management in the Uniquity Dream Machine).

I even tried other sdk versions (and from different locations and networks: friends house, my phone, ect) and none were fast hinting to an upload speed issue from Nordic file server side. 
Even ChatGpt said this is a known issue for many users and is slow (see one screenshot of many) 

Please can the nordic team investigate on their side in terms of the server's upload speed. 

Kind Regards,
Tristan

I got my Macbook Pro M4 on Friday, so tried it from home network without any VPN installed yet. But if you think others have seen this aswell, then I can query this internally and come back to you with more information if anyone else have seen this before.
