Ah-ha! The mystery internet saboteur has been unmasked—your ISP is the culprit. What’s likely happening is that the ISP is either meddling with encrypted traffic or has something funky in its routing to Cloudflare that breaks SSL.
Moving forward:
- For now, stick with the VPN to complete the AMP installation and setup. At least we know the VPN bypasses the issue entirely.
- If you’d rather not rely on the VPN long-term, you may want to call your ISP and ask why they’re blocking or interfering with legitimate HTTPS traffic to Cloudflare endpoints. They’ll probably shrug and say it’s not their fault, but it’s worth a shot for permanent fixes.
Let me know if you hit any further snags during the install. Otherwise, go forth and build your AMP empire!
