Join-server returned error: http post error: Post "https://chirpstack-application-server:8003": dial tcp: lookup chirpstack-application-server on 127.0.0.53:53: server misbehaving"

Hello All,

I am trying to activate my Ursalink make Temperature & humidity sensor over OTAA. But under device data tab of the App server web interface i am getting the following error :

join-server returned error: http post error: Post “https://chirpstack-application-server:8003”: dial tcp: lookup chirpstack-application-server on 127.0.0.53:53: server misbehaving"

Seems like an issue from join server.

Can anybody please help me? I am stuck in my official project.

Thanks in advance
