standalone clients or web clients? For web there’s websocket proxy which has it’s own WebSocketProxyTicketValiditySeconds engine-config parameter
But I think the regular 120s for the actual qemu connection still applies, so it won’t solve anything for you
120s cannot be changed

Note that if your clock between engine and hosts is too much off you will run into all kind of issues. So please do make sure you have NTP set up on all machines correctly.
For clients connecting to portal/console it’s indeed just this ticket validity which is often a problem:)
