LTE interface not working

Hi, since my last question for rebooting i found some scripts and managed to restart the router frequently. But during try and error something must went wrong, because I lost the internet connection via LTE interface. It starts properly, sends and receives data during start-up and has also a proper Info.
But no IP finds its way out, there is absolutely no traffic at the LTE interface when the internet should be connected. So I think its a routing problem.
I copied teh settings from the terminal, maybe for a specialist its easy to see where the problem is…
