It looks like the guide catheter was stuck in the radial artery. Spasm could be a factor and sometime the edge of the guide catheter (which is a bit sharp) can make advancement hard.
Tip:
So, all the above suggestions are reasonable and worth trying. However, another technique you can do is to advance an interventional guide-wire into the guide catheter, then advance a balloon over it and make part of it inside the catheter and the other outside it, then inflate that balloon to a low pressure, after that you may be able to advance the catheter and the balloon together (Watch attached video).

Inflating the balloon and advancing the guide is a risk to scrape and damage the vascular system .
AUCATH guide Hydrophilic works 100% of the time

Thanks @Khaled Sleik . Will try it in future. Thanks for the tip!
BAT (Balloon assisted tracking) is my first choice , it works most of the time
