Forest [Ps4] Couldn't create PSN lobby?

When I was playing The Forest [multiplayer] this morning, everything was still working.

But when I wanted to go online again it says:

PSN lobby could not be created.

Closing the game and restarting the console did not help.

Has anyone ever had the same problem?

If so, what can I do to be able to play online again?

Take a look at your MTU or whatever you call it.

Thanks for the answer, my problem has now been solved. Since this morning it has been working again as if nothing had happened, but what it was now is unclear. I don't know where the problem was. Anyway, thanks again 👍🏻
