Why can't my Epson XP-255 connect to my Wi-Fi?

When i wanted to connect my printer to my router i followed the instructions exactly. I pressed the Wi-Fi button, the WPS button on the router and then everything should go by itself. First, both LEDs alternately lit up, as it should be.

Now they both look at the same time and that for about 30 min. When I search for my printer on the laptop, it finds it, but tells me that I should follow the printer instructions to connect.

But there's no haha. I don't understand why things go wrong, I did everything as it was described to me. What can I do now?
(by the way have a windows 10 laptop)

Thanks a lot.

This may be blocked by the router.

Check the settings to see if you can connect.
It may be that the router does not allow any further connections

Print a network status sheet. Press the button to the right of Wi-Fi for 10 seconds.

Strangely, he doesn't want to print them.
