所以这是我的问题：我使用令牌生成了一个ChatClient实例，我想使用接收到的SID失败的实例加入该实例，并且出现以下错误
2019-01-25 16:37:17.812 15294-15294/com.twilio.chat.demo E/TwilioApplication: Login error. Error 0:1401 Unable to establish connection to Twilio Sync service

我已经从twilio网站开始使用twilio chat quickstart android了。 我还创建了访问令牌URL来检索令牌。下面是我用于twilio聊天集成的主要活动代码。

嘿，在设置Twilio演示聊天应用程序时，我也遇到了这个问题。我正在使用https://github.com/twilio/twilio-chat-demo-android Android应用程序和https://github.com/TwilioDevEd/sdk-starter-ruby。我花了一点时间才发现我设置了ACCESS_TOKEN_SERVICE_URL=http://abc12345.ngrok.io，而不仅仅是将ngrok复制粘贴到我的kotlin应用程序gradle.properties文件中。当我应该查看sdk-starter-ruby应用程序中定义的路由时。在这种情况下，sinatra应用定义了一条路线
get '/token' do
# Create a random username for the client
identity = Faker::Internet.user_name
# Create an access token which we will sign and return to the client
token = generate_token(identity)
# Generate the token and send to client
json :identity => identity, :token => token
end
这是我需要作为该属性的URL输入的路由。
因此，这为我解决了该问题ACCESS_TOKEN_SERVICE_URL=http://abc12345.ngrok.io/token
您的SERVER_TOKEN_URL转到https://example.com/chat-token，因此应该指向生成令牌的服务器。这里有多种语言的示例：https://www.twilio.com/docs/chat/javascript/quickstart
