SSL Error #122

Open MrXyfir opened 5 years ago

MrXyfir commented 5 years ago

This occasionally pops up in my error logs:

Error: 139783281137472:error:142090FC:SSL routines:tls_early_post_process_client_hello:unknown protocol:../deps/openssl/openssl/ssl/statem/statem_srvr.c:1638:

Error: 139783281137472:error:1420918C:SSL routines:tls_early_post_process_client_hello:version too low:../deps/openssl/openssl/ssl/statem/statem_srvr.c:1663

Everything appears to work but clearly some clients are having issues. Is this worth worrying about?

Maybe it is problem of tls 1.0. TLS 1.0 is disabled in node 12.

I can not upgrade to Node12 from Node11. :sob:

I think this is SSLv3 related, or openssl version mismatch between servers, or some other issue related to deprecated protocol such as SSLv3.
