Error while upgrading firmware

I’m trying to upgrade the firmware from EG915UEUABR03A01M08_01.203.01.203 to EG915UEUABR03A01M08_01.209.01.209 through https and I receive the following response
Screenshot 2024-03-26 104332
And as further as I know from the firmware upgrade form, this 1 indicates to an abnormal datacall.
How to solve this?

Hi @asmaa
Can you upgrade locally? If it is possible to upgrade locally, I will send you the complete firmware package so that the upgrade is more convenient.

Hi,
I need to do it via FOTA not locally unfortunately
