-100 Error When Accessing Private Platform Page
1. Problem phenomenon#
(1) Why does Error -100Error appear when using Tingyun for monitoring?
(2) In the monitored data, Scatter Plot is a green dot, and the error report should be a red dot.
2.Problem analysis#
Through packet capture, client Logdebug.log and analyze.log, and using different versions of chrome (72 and 79 versions), we found that the client sent client hello, and the server responded with server hello. Before the client continued to respond, the server sent a fin packet to end the connection. Connecting Exception caused the client to reconnect. Even if the connection was successful, there was a 12-second handshake time.
first,
second time
third time
**The client needs to adjust the server. **
