Ec25 sometime no connect to internet

Hello
I have a Ec25 module, a linux embedded system and I use GobiNet driver, quectel-CM
All works well but sometimes during a day the module never connect to internet for 2 o 3 hours and
I have the following log:

What is the error 0x5a ?
CREG, COPS and CSQ are all ok but the internet connection dosen’t start.
This does not seem like a configuration or software problem because without changing anything at some point the connection restarts

Hello, I also think it is not the configuration or network problem according to your description. Now we have a new firmware version, and some network problems have been optimized. Do you need to upgrade to the new version to confirm whether the problem has been solved? If necessary, please provide your email address and I will send you the new version.

Hello
my mail is anna.scuderi@connetweb.com
Can you send me the instructions for install the upgrade on the module?
Thanks
Anna

Hi,I send it to you,Please check.

Thank you but are you sure the is the correct version for my module Ec25-e ?
The version name is completely different from the previous one
