Cosy 131 Problem with 4g internet conection

Hello,
I have a problem setting the parameters of my local internet provider (Plus poland) with cosy 131 modem. I have tried all the APN settings but none work.
This is already frustrating, my previous ewon flexy was connecting without a problem.
Below are the logs
wanmgt-WAN connection request has time out
esync-Cannot establish WAN connection
Kind regards Kamil

Hi @Kamil_Kielbasinski,

I would recommend creating a backup with support files by either going to the Diagnostic > Support Files screen, or using eBuddy to make the backup and checking “Include Support Files”. Then create a case at support.hms-networks.com and attach the file. They should be able to help you better as they will be local to your area and more familiar with the local service providers.
