WebSocket connection to ‘wss://xxx.com’ failed: Error in NET::ERR_SSL_OBSOLETE_VERSION

原因:chrome 升级到84版本后,默认启用Tls1.3加密协议,废弃了Tls1.2|1.1|1.0协议,由于浏览器服务端(Tls1.2) 与 客户端(Tls1.3) 加密协议不一致导致握手失败

解决方法:
chrome://flags/#legacy-tls-enforced
Change the setting for “Enforce deprecation of legacy TLS versions” from ‘Default’ to ‘Disabled’
Restart Chrome
