I think your ICAL URL might be wrong. Check that URL with the default calendar model. (See the log - what the module said.)

And, I don’t recommend putting the upcoming view into the horizontal region. upcoming view has only one slot so it will not match with the horizontal layout. upcoming view in the vertical region or daily view, weeks view in the horizontal region is better.
