Summon don't work after update

Hi,

My production GenieACS was 1.2.8 (needed to keep it because of custom change to the code to accomodate issues in a legacy device model) and I want to update it to 1.2.16.

I also needed new package like axios for external script so I build a new container with everything up to date.

So, I have 1.2.8 and 1.2.16, side by side, on 2 differents container, configure to use the same DB. Everything work fine. I can summon devices from both container.

I shutdown 1.2.8 and move the ip address from 1.2.8 to the 1.2.16 container and I can’t summon devices anymore. I get the following error:
DeviceID.ID_value: No contact from CPE

I move back the IP address to 1.2.8 and both can summon fine again.

I’ve made a network capture from the ACS server and looked at it. Here is what I see

Packet 1 from server: GET /tr069
Packet 2 from the CPE: 401 Authorization Required
Packet 3 from the server: GET /tr069 with Digest auth
Packet 4 from the CPE: HTTP 200 OK
Paquet 5 fromt the CPE: HTTP/XML POST
Server don’t answer back but it indicate on the UI “No contact from CPE”

Debug output:

I’ve been testing it for days, trying to figure out why with Claude and Gemini help but both clearly don’t have any idea of what going on.

What I have is mind is maybe edit DHCP config so ACS discovery to use a new IP address for the ACS server and hoping that it will create a bootstrap event on the CPE to clear everything because it change of ACS server but that a lot of job (several DHCP server) while I’m not even sure it will work.

Anybody have a idea of why it won’t work ? Any hint would be greatly appreciated.

P.S. Periodic inform don’t seems to generate fault. I see the last periodic informs being updated on 1.2.16 but I have no way to be sure the config is really updated on CPE if needed.

Finally, I was never able to fix this issue so I changed the ACS discovery config to point to a new URL and it seems to work fine. Still have some site left that I must change the ACS discovery config but I tried to shutdown the old server container and I was still able to summon devices on the updated one.
