I think you should read documentation about CoA offered by your NAS.

Then see what can likely be about *Missing Attribute* at least. You better know about all of Error-Cause it may occur.

In my experience, it might be lack of key on identifying unique host.

In other words, could it be your Acct-Session-Id or User-Name cannot be primary key to identify one host on the NAS?

What kind of CoA server you are using? In my experiences, coa highly depends on the type of NAS. In my case that I has a WiFi GW as CoA server, it usually gets "Missing Attributes" if I missed some *keys* of identifying unique user. Such as "NAS-IP-Address + NAS-Port-Id" or "Some-VSA-Can-Be-A-Key" or "Acct-Session-Id" and usually with priority.

Besides, maybe you can post some more detailed output of your testing so that we can do more help.

Okis.
