Hi everyone,
I’m looking for insights into diagnosing TLS handshake delays and inconsistent performance across different client devices when using NGINX as a reverse proxy. In some setups, websites perform perfectly on Windows and Android clients, while certain devices (especially with stricter TLS implementations) experience slow page loads or intermittent timeouts.
I’m particularly interested in best practices around:
-
TLS protocol and cipher selection
-
MTU and PMTUD-related issues
-
HTTP/2 vs HTTP/1.1 behavior
-
Network path differences (ISP, router, firewall)
Real-world troubleshooting experiences or configuration tips would be greatly appreciated, especially cases where the issue wasn’t immediately visible in NGINX logs.
On a lighter note, dealing with infrastructure cleanup often reminds me that operational hygiene matters everywhere — whether it’s servers or real life tasks like arranging reliable final cleaning services after a move.
Thanks in advance for your help!
