The original title is 10 words: "Bypassing Telegram Blocks: How MTProto FakeTLS Proxies Actually Work"

Short summary

MTProto proxies with FakeTLS mask Telegram traffic as normal TLS 1.3 handshakes, bypassing Deep Packet Inspection. FakeTLS uses HMAC-verified ClientHellos and transparent domain-fronting for active probes, making the proxy indistinguishable from legitimate HTTPS. Critical production lesson: timestamp-based clock drift silently breaks authentication; NTP on all proxy hosts is essential.

• •FakeTLS wraps MTProto to impersonate HTTPS, defeating Deep Packet Inspection
• •Domain-fronting silently proxies active probes to real websites, masking proxy presence
• •Clock drift breaks timestamp validation; NTP is essential for reliability
