The event message sent from the server is lost.

[ChanryX]

I should receive four event messages from the server on the client, but I only received three. I have printed relevant logs in the void connection<config>::handle_read_frame(lib::error_code const & ec,size_t bytes_transferred) function, but I cannot find deeper problems. I would like to ask how to get the bottom-level data frame and some error troubleshooting methods. Thank you.

How many messages does Wireshark show?
