Hi There, I can’t figure it out what is missing or if I did something wrong, I use the migration tool and everything went well, before migrating all my devices were up and running, now my gateway can’t connect, I am using a pygate with a lopy4 for an as923 band. and few pysense’s with lopy4’s as my nodes here are my configurations if somebody could help me
