Latency problem, HELP!

Hey guys!

Sooo I know Australians seem to be having a lot of problems with latency. Any Europeans out there with issues too?
I live in The Netherlands, and I am having lots of laggy matches on my own end.
Sometimes I have green bar matches with no problems whatsoever. Then the next match: constant red bar and hitting projectiles is incredibly hard (especcialy apparent when throwing Deande’s fans)
It’s so bad that playing melee and precision characters is almost impossible.
I don’t know why, honestly. My internet is fine: PS4 is wired, has type 2 NAT and plenty of mbps.

If anyone has any idea how to help me, please let me know!
