Cloudflare servers in India get MITMd by the network provider If the upstream is github pages and configured without end-to-end TLS.
Switching the upstream from Flexible SSL to Strict tends to fix this.
None of this was happening in previous deployments
Using a VPN bypasses the block

cobalt.tools is configured with strict tls
this seems more like a cloudflare issue than some sort of MITM, because there is nothing to MITM (the frontend is served by cloudflare itself)
