nRF9160 https_client sample error

[npd]

Toolchains: v2.5.0

SDKs: v2.5.0

I followed this sample code https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/nrf/samples/nrf9160/https_client/README.html on an nRF9160DK. However, I got a connect() failed, err: 113. I'm not sure what is wrong.

This post is about the same error code. The post is about a different board, but perhaps the same solution might work in your case? (Downloading new certificates)
