Looking at the route table in the screenshot you shared I see there is an entry for 10.2.0.0/24 with local route (gateway 0.0.0.0).

This is the reason why the instance attempts to directly ARP resolve the 10.2.0.35 IP address instead of sending it through the next-hop gateway.

I'm not sure how that entry got in your route table but one you will get rid of it I expect the problem to be resolved.
