Exception of CDN's SSL expiring is not handled

[bluems]

My guess is that the project acquires files for offline use from the CDN specified in the user's FASTAPI.
I am getting the error below, I am not able to clone the files from the CDN the same as FASTAPI.
This project needs an option to change or specify the CDN.
