Cant retrieve files from objects.githubusercontent.com - Connection Refused

Hi,

I am facing a strange issue. I cant retrieve files from topic URL. All them fail with a connection refused from the four ip addresses resolved in the DNS query:

I can do it from any other location I have access from

I was experiencing this same issue from this (101) location past month, but it was spontaneously fixed. Problem persists in this (501) location.

Anyone has experienced the same?

Thanks in advance.

Kind regards,

Miguel
