Operating on a VPN or proxy is fine when I'm browsing and surfing, but certain sites will change the content based on the geographic location associated with the IP address of the VPN/Proxy Server, and several accounts will refuse to log in without multiple tedious verification measures. Something I did must have led to this initially, but I don't know what. What matters is this:
• Using my home Wi-Fi, not a workplace network.
• No problem connecting from any device. Lately, however…
• Previous MacBook Pro would connect successfully, and would show that there was full signal, but…
• Many webpages cannot load unless I activate my browser's Proxy IP or my computer's VPN, and…
• Even email, the App Store, and various internet-connection-reliant applications and services would fail to connect. Being unable to connect to iCloud was probably the most frustrating.
• Despite having migrated to a new MacBook Pro, the error transferred itself along with almost everything else– but the new computer's internet operation worked just fine before any data migration!
I don't experience this with any other device in the house. This is a software-related issue, since it occurs on different hardware running a cloned system.
What locations (within the system, utilities, libraries, etc.) might inspect to identify what exactly is causing this problem? What are some tools that can help diagnose this?
