This issue is similar to GitHub issue #67.

we are working on reproducing it at our environment. If i may ask, is there any environment setting at your host?

#4

No. We all followed the instruction.

My environment:

Ubuntu 18.04
Memory: 4GB
Processors: 4
Hard Disk: 32GB

Do you need any information to check? Maybe we can help about that.

#5

How about try replacing git.cs.nctu.edu.tw/calee/sctp to github.com/ishidawataru/sctp in free5GC.

#6

Sorry. Still failed on test.sh. It can’t work.
Or maybe I can send you the vm image?

#7

It might be less helpful sending us your vm image, because we cannot reproduce it on our own here.

My other point of concern is the bug might be cause by the hardware. Can you please cross check your hardware specification and see whether it might have been the leading caused.

#9

Dear,
if your problem get resolved, please do update us. we are also waiting for the solution of the same problem. :smiley:
Thanks

Sure, we’re still working on it any new development we will update it on the forum. Thanks to @ouyang for supporting with his VM for our team to work on reproducing the error.

Hi @ouyang,

We found out that you are not using the latest version of free5gc (v3.0.2).

You might try checking-out on v3.0.2 and test again, probably v3.0.2 default is using H2C in SBI. Finally try using this command mongo --eval "db.NfProfile.drop()" free5gc to flash the data in db

#12

Hi @vikash,

what version are you currently using?

#13

We found the root cause of the issue.

Based on our finding we observer that, after running TestNon3GPP, the test script will trigger a modification on ngaplpList. Although the script will auto recover the amf config file but when the test is terminated manually the ngaplpList will not be recovered. Therefore, if tried with other test for instance, (TestRegistration) the sctp will bind to an IP’s that are not existing which might result to failure.

To our conclusion, the issue might not be related to version difference. Please refer to the troubleshooting instructions below for more detail.

Refer to the trouble shooting:

Sorry, but I don’t have the file which named amfcfg.conf.bak.

How should I do?

#17

You can try to use the original amf config file.

I also got the same error on 2022/3/14. Any help is appreciated~

Here is my error code

I also got the same error.
I’ve been following the YouTube videos, but haven’t made it past Video 10: Testing free5GC due to failing “./test.sh TestRegistration”.
