WAN not connecting, Stuck on Connecting & Showing Roaming Signal

I have a Tmobile Static IP with Custom APN through KORE wireless.

I’m able to get Verizon and ATT to work with them,

Working with their support, I was able to get the unit to connect 1 time and haven’t been able to since.

See below for settings and picture of issue,
