Hi, community!

When a user accesses the eSight page, the bad gateway (error code: 502) error message is displayed.

Please help me, thanks!

Hi friend!

Possible Causes
The Transmission Control Protocol (TCP) port resources of the eSight server are insufficient. When a large number of clients access the server concurrently, the server operating system (OS) generates a lot of TCP connections in the TIME_WAIT state, which consume TCP resources. By default, the OS recycles the TCP connections in the TIME_WAIT state 4 minutes after they are generated. As a result, TCP connections are recycled slowly, which leads to a throughput decrease.
Procedure
For details, see 2.2.1.3 How Do I Reduce the Time for Canceling TCP Connections in TIME_WAIT State on Windows? or 2.2.2.7 How Do I Reduce the Time for Canceling TCP Connections in TIME_WAIT State on Linux?.

Glad to help!
