LTE Connection Timeout Error (-116)

Use nrf_modem_lib_init() to initialize the modem, followed by lte_lc_connect() to connect to LTE. However, it consistently fails to connect to LTE. After it times out, the serial log displays:



This issue has only started occurring in the past two days. There haven’t been any significant changes to the program, and even minor changes did not involve the modem-related code.

I’m quite confused about the cause of this issue and hope you can provide some guidance.

Thank you for your help,
Guo Qi
