Why do you think it's due to that change and not a network and/or Gerrit hiccup?

Because I've never had an issue with this script and now it's consistent and such scripts are notorious for breaking on Windows... so I went with the latest change...

Bisecting locally, it's caused by https://chromium-review.googlesource.com/1173069, apologies for the initial missassignment, hadn't realized there'd been lots of recent changes in this file.

So review.coreboot.org uses a lets encrypt cert. If it's not in the root store then I think you get that error. This cl added the key to the store https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/1173064 

Your error says WARNING:root:Consider installing python-keyring, is windows using a different keystore?

I don't know how the keystore works on Windows. This warning has been there
forever and has never been a problem for me. I think I tried installing
that package on Windows in the past and failed (didn't bother to figure it
out)

Which python are you using? Is it the one that comes with depot_tools?

Looks like it :

$ where python
D:\src\depot_tools\python.bat
C:\python_27_amd64\files\python.exe

let's revert for now, and rrangel@ can you reformulate as a platform-specific patch. I'll have to investigate the depot_tools supplied python, which I think should support this certificate (but it might be too old)

Revert "my_activity: Add review.coreboot.org as a source"

This reverts https://chromium-review.googlesource.com/1173069

It breaks my_activity.py on Windows.
