error -111 means connection refused and is probably caused by incorrect root CA certificate for MQTT and HTTP.

When nRF Cloud multi-service sample provisions the device to the nRF Cloud it uses UUID for device identification. If the sample is rebuild without provisioning overlay IMEI is used for identification. This causes the connection issue. Please add below kconfigs to prj.conf when building the sample without provisioning overlays

CONFIG_MODEM_JWT=y

CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y

Hi,

[quote user="PhilWare"]from this log it is clear that the LTE-M connection is not very good at all and is probably causing the flaky connection issues.[/quote][quote user="PhilWare"]I will try in a better location and hopefully that will work better [/quote]

For comparison, please provide your testing results from different location.

Best regards,
Dejan

I'm not sure why I am now seeing a different error code (-111), but from this log it is clear that the LTE-M connection is not very good at all and is probably causing the flaky connection issues.

I will try in a better location and hopefully that will work better 🙂

Hi,

Can you show complete build command which you used?

There are some useful debug options in documentation. Can you try to enable debug logging for the sample using CONFIG_MULTI_SERVICE_LOG_LEVEL_DBG=y and provide new log?

Best regards,
Dejan

I was referring to the partial log which you sent in your initial post. I am interested in seeing also the lines before "<err> nrf_cloud_transport: MQTT input error: -128".

I am using v2.9.0 and the application always returns this MQTT input error: -128, right from the start.

I have unclaimed the device and then re-claimed it thinking it needs to go through provisioning, but that is not the case.

I believe it is connected to the cellular LTE-M network as it says it is, and +CEREG? returns '1'. I also suspect the nRF Cloud connection isn't attempted unless there is a cellular connection.

Hi,

[quote user=""]The application runs OK and connects to the LTE-M network, but with my own compiled version I am now getting this error[/quote]

Did application run OK for a while and then stopped working suddenly?

Which NCS version do you use?
