LoRa E5 - Cannot join

Hi, community. This is my first post about LoRa so… let’s do it!.
I have a problem with LoRa E5 module. After configured DR, CH, APPKEY, (I’m working with EU868), i try to connect the module with own LoRa server but it faul.


Look at imagen, the data recived by LoRa E5 is “join… join…join…” and it never stop. Anybody have the same problem? because in other module (I have 2 module working) it can join to the server.

Thank you all.

With AT+LOG=DEBUG, this is the answer:
