I believe the issue is with some UE not all of them. Unfortunately there are a lot out there I have to deal with.

I have used baicells CPE and it got attached having used the default "internet" APN setting .

Hi David,
Baicells CPE has "internet" set as APN by default.
And you can make changes to the APN name under APN management field.

I will get you a pcap. The UE actually don’t have an APN listed by default.

Even though UE try to connect without APN, if you set the first APN(default APN) to the mongoDB, open5gs won't reject the UE request. If the problem is still not resolved, I need your pcap file to fix the issue.

I figured out what was going on, so perhaps there is a solution already in place. By default the Baicells UE do not request a specific APN. That causes the EPC to reject the request.

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
