reporter   ~0000932

There is no serial number defined on the acs server
Each time the serial number connection is sent and then defined
The initial serial number and oui (FFFFFF FFFFFF123456) were not defined, but the connection was established

After I switch the serial number to FFFFFF123456 and OUI to FFFFFF and restart EASYCWMP worked correct


2019-10-07 15:01

administrator   ~0000941

May be your acs accept only serial number in hexadecimal format

So how does this accept defaults?
Does this mean FFFFF and FFFFFF123456?


2019-10-07 15:32

administrator   ~0000943

by the way OUI should be hexadecimal
FFFFFF is hexadecimal
KKKKKK is not

I tested with this one but still get the Error 403
serial: BBBBBB123456


2019-10-07 15:42

administrator   ~0000945

You have to check with the ACS provider


2019-10-07 15:45

reporter   ~0000946

But I find no reason for this
If acs has problems I shouldn't connect to it even with oui FFFFFF and serial FFFFFF123456
But what happens to ACS after the change? Unchanged ACS This is caused by a change in easycwmp


2019-10-07 15:58

administrator   ~0000947

I checked the inform message sent by your device. ANd there is no issue with it. The issue is from the ACS, because the issue is returning forbidden 403 when OUI is BBBBBB

These acs set the username and password according to oui and serialnumber
And I found that by installing easycwmp even by modifying the modem it recognizes me as the previous modem.
Isn't that the solution for it?


2019-10-07 17:51

reporter   ~0000949

What I do notice is that the server always recognizes me as a similar modem it has previously identified
Is there a solution to this?

administrator   ~0000950

This is really ACS issue, you nead to understand the ACS behviour and configure easycwmp and ACS in the right way.

What is your ACS?


2019-10-07 20:23

administrator   ~0000951

OK , I see you are using AV system, easycwmp was tested successfully with AVSystem

Thank you
Does that mean you don't have a solution to solve this problem in easycwmp?
