SECURITY PROXYCHECK SET CHECK-TIMEOUT
Usage: SECURITY PROXYCHECK SET CHECK-TIMEOUT [seconds]

When the proxy scanner is enabled, the server will not allow connections to the server to complete before the proxy scan completes. This option allows you to set a ceiling on the amount of time the user will wait. If the proxy scan does not complete within the allocated time, the connection is resumed.

Example:
/as security proxycheck set check-timeout 30
