I am assuming there is a typo in your Java version and you are using Java 8. That Tomcat version is over 3.5 years old (and Tomcat 7 is EOL in less than 6 months). If you aren't already planning to upgrade (I'd suggest to 9.0.x) then you might want to start thinking about it. I have a few ideas about what might be going on but rather than fire out random theories I have some questions that might help narrow things down. 1. If this request was successful, how big is the response? 2. If this request was successful, how long would it typically take to complete? 3. Looking at the Wireshark trace for a failed request, how long after the last byte of the request is sent by the client does Tomcat send the FIN? 4. Looking at the Wireshark trace for a failed request, is the request fully sent (including terminating CRLF etc)? 5. Are there any proxies, firewalls etc between the user agent and Tomcat? 6. What timeouts are configured for the Connector? 7. Is this HTTP/1.1, HTTP/2, AJP, with or without TLS? 8. Where are you running Wireshark? User agent? Tomcat? Somewhere else?
