FMC130 Problem APN

Good morning,
We are dealing with a problem related to Teltonika FMC130 devices (SLM320 modem version). We have noticed that when the devices have no APN assigned to them, the connection is established without any problems. However, when trying to configure an APN, our logs show that it is not possible to establish the connection due to a device error. It seems that the APN configuration is not working properly.
Sincerely, Sergio Mesa
