Ewon 4G with antenna gets disconnected form SIM internet after powercycle


I’m trying to set up a couple of Cosy’s 131 4G in Sweden. I actually set them up, but when restarting (due to power off the panel or any other thing), the ewon does not connect anymore to internet and says at the summary: Internet Connecion Error and Fallback: disable …It does not connect anymore until I take out the antenna, and then I have to put it awaing after some seconds. This does not seem a normal behavior, is there a way to make this get connected without having to open the panel?

Also, similar thing when setting them up, I have to do it first without the antenna or else it will say there is no WAN connection… after seting it up I put the antenna it goes OK, but this need to be done in a place with a lot of service so the ewon can take internet.

Attached support file after restarting and taking out the antenna.
