Access to Amazon, AWS, etc. webpages fails
I have a vexing problem. On my laptop, I cannot access any websites from Amazon, including amazon.com or any aws websites. The browser (does not matter which) simply says that the website cannot be reached. It does not matter whether I use my home wifi, a mobile hotspot or some other sort of (wireless) network (I do not have access to a LAN at the moment). Interestingly, when I use the VPN of my university, everything works fine.
I have flushed my DNS cache, checked the hosts file, but cannot find a problem. Does anybody have an idea?
