Re: Reject message

27 Mar 2020

Hi david,

If pcap is provided, it is more easier to analyze your problem.

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.
It means that UE APN is unknown in HSS. So, you need to match APN name
between UE and HSS.

Thanks and regards,
   Sukchan
