After some hours debuging, I releazied root cause of problems is replay protection cache in Gateway. If replay cache is full, gateway will discarden-USTelligent Community 13Fri, 10 Jul 2020 08:35:46 GMThttps://devzone.nordicsemi.com/thread/259377?ContentTypeID=1Fri, 10 Jul 2020 08:35:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:213c9017-393b-499b-bc73-2c0a7d4df19ftesc<p>Hi,</p> <p>Gateway discarding message because of full replay cache does not quite make sense to me. If anything, message would be discarded because the exact same message has been previously received - or the new message uses a sequence number lower than a previous higher sequence number from the same sender.</p> <p>Can you point out to me in the code, the issues that you found with replay protection cache, and how it happens?</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
