Thingy91 lwm2m FOTA update

[Hkhan7861]

Good day 

I am trying pull an update from our own server using lwm2m and have attempted to follow the steps accordingly.  The sample I'm using is the standard lwm2m client sample.  I seem to  be getting an error which is documented as a connection timeout.  Any ideas on what I need to do ?
