在最新的Bot Framework Emulator 4.0.0-preview.40025中（尽管在我尝试的每个版本中都发生了此错误），但出现以下错误：
[11:37:11]Emulator listening on http://localhost:65141
[11:37:11]ngrok not configured (only needed when connecting to remotely hosted bots)
[11:37:11]Connecting to bots hosted remotely
[11:37:11]Edit ngrok settings

[11:37:11]request to https://localhost:44378/api/messages failed, reason: unable to verify the first certificate
原始的V3 Bot框架模拟器可以正常工作。
任何帮助表示赞赏。
