Electronic device and control method thereof

An electronic device, comprising:

• a memory storing information related to a relay device;
• a first communication interface comprising circuitry;
• a second communication interface comprising circuitry;
• and
• a processor configured to:
• control the first communication interface to communicate with the relay device,
• control, based on a signal notifying communication connection failure between an external device and the relay device being received from the external device through the second communication interface, the second communication interface to transmit a signal requesting entry into a specific communication mode to the external device, wherein the signal notifying the communication connection failure comprises at least one of identification information of the external device or information related to a cause of the communication connection failure,
• transmit, based on the external device being identified as entering the communication mode, information related to the stored relay device to the external device through the specific communication mode,
• identify a device comprising a display from among at least one device registered to a same service account as the electronic device, and
• transmit, to the identified device, a signal notifying the communication connection failure comprising information related to a cause of the communication connection failure based on the signal notifying the communication connection failure being received from the external device.
