由于Heroku会弃用我的应用程序使用的Redis版本（5.0.12），我升级到了Redis版本6.2.3。
从那时起，WebSocket立即在我的客户端中触发onclose回调。

以settings.py为单位的通道_层值

这是一个老问题，但对于任何其他人面临类似的连接错误Heroku让你参考文档：
从Redis 6版本开始，爱好计划支持TLS和非加密连接。生产计划需要TLS连接。您必须在Redis客户端配置中启用TLS，才能连接到Redis 6数据库。更多信息，请参阅Heroku Data for Redis Security and Compliance。
所以换句话说，如果你的Redis示例在生产计划中，请确保你正确设置了TLS。
如果是这种情况，因为你使用的是Python/Django，你应该引用：https://devcenter.heroku.com/articles/connecting-heroku-redis#connecting-in-python
