Autoprovisionong T4xS v83 error

[gasper_s]

Hello,

does anyone know if there was any change in auto provisioning for firmware version 66.83.x.xx for T4xS phones, because it stops working after upgrading.
I searched documentation and forum, but couldn't find anything.


I have phones T42S, T46S and T48S.

In my y0000000000xx.cfg files I tell them to upgrade firmware:
firmware.url = tftp://172.16.xxx.xxx/T4xS-66.83.0.10.rom

It all worked fine, but after upgrading to 66.83.0.10 it stopped working for all phones.
On phone I get message: "Unable to complete. Will try again now!"
On TFTP server I get message: "TIMEOUT waiting for Ack block #1"

I tried to upgrade to 83.0.10, 83.0.20, 83.0.35 and 84.0.10. It all works from v82, but after upgrade to any of these firmwares, it stops working.

I can still do manual firmware upgrade and downgrade via web browser, but it doesn't work via TFTP autoprovisioning any more.

Does anyone else have this problem?
Any help would be appreciated.
