Hello,
we are using JSC for a few years with a SRX340. Yesterday we've upgrade from 23.4R2.13 to 23.4R2-S5 without changing anything on the configuration.
Since then, when we are using JSC, we can still connect successfully but immedialty after, the client disconnect and reconnect and so on.
This is what we got on the client side :
24/03/2026 09:24:41 - SUCCESS: Link -> <vpn.company.fr> IP address assigned to IP stack - link is operational.

So it seems that the SRX is reseting the SA session but I cannot understand why ?
Thanks for the help :)
