Slicer tutorial error

Hi everyone,
I am experiencing some issue when trying to access slicer training modules. I am running into security issues to access that saying connection is not private and does not use https. I tried chrome and microsoft edge and also disabled antivirus but still not working. Attached is the screenshot.
This is something new and was not there last month. Would someone pls help.

Thanks,
SarvCapture

What link are you trying to reach?

Hi Pieper,
Was trying to access 4 minute tutorial. It was a dropbox link but getting that error message.

Thanks,

Hmm, this link worked for me:

https://www.dropbox.com/s/9jfsyhhgude5hf1/Slicer4.8minute_SoniaPujol.pdf?dl=0%7C

It worked for me, too.

Note that what you see is not an error, the link works, you just get a security warning because for some reason the top-level security certificate is not trusted. You can click on Details and proceed to the page anyway.
