how to fix: Failed write of Log Event: {"text":"The requested URL was not found on this server.","code":404}

[steveIMS]

I have Java program accessing HTTPS the HEC with Token; I have tracing on for the SSL Handshake; it goes thru handshake,

*** ClientHello, TLSv1.2
*** ServerHello, TLSv1.2

when actual event is written, then get:

Failed write of Log Event: {"text":"The requested URL was not found on this server.","code":404}

Reply: {"text":"The requested URL was not found on this server.","code":404}
ErrorCode: 404
Failed write of Log Event: {"text":"The requested URL was not found on this server.","code":404}
OkHttp ConnectionPool, called close()
OkHttp ConnectionPool, called closeInternal(true)
OkHttp ConnectionPool, SEND TLSv1.2 ALERT: warning, description = close_notify

So the HEC acknowledges both the client and itself, then fails. Anybody know what this issue would be? Thanks, Steve.
