I’ve been developing the tutorial “S1TBX StripMap Interferometry With Sentinel-1 Tutorial”, develop the passage of coregistration using images in Puerto Lopez Colombia:

S1A_IW_GRDH_1SSV_20151005T230455_20151005T230524_008024_00B3BB_3441.SAFE

InSAR is only possible with SLC (Single Look Complex) products and you are trying it with S-1 GRD (Ground Range Detected) products. Please download the corresponding SLC-products and try again.

I think we could make the error-messages more informative than that @lveci
