Crashed ships don’t show up when you walk through a portal. In order to acquire this ship you can do one of the following:
1. Go through the portal and set a custom waypoint on the Galactic Map from the Discoveries menu. Then return to your original planet, go to space and follow the custom waypoint path to this planet (could be a long way depending on where you are in relation to this region of space).
2. If no other player bases are in this system you can go through the portal and claim a temporary base on this planet (suggest turning Base Sharing off while you do this). Upon returning to your newly-claimed temporary base, the crashed ship will show up.
