I’m having trouble with Fortnite Battle Royale on PlayStation 4, something I never had problems with on Xbox One, and I’m coming here because my ISP has been no help what so ever, So I’m hoping someone with enough experience could help me identify the problem and report it to my ISP so they can fix it or maybe I could fix it myself throughout my Antenna, I have full access to my Mikrotik Antenna just so you guys know, and I think I narrowed it down to a certain port being blocked but I’m not sure which port it is, is there any way to monitor ports that got blocked or denied from having access ?
Any help will be very appreciated
Thank you,

If you are mildly connected to social media you probably will have seen that Fortnite servers went hard down over the past few days with significant downtime as well. Probably related to that if it has been working fine previously.
Also, please provide more information, so others can actually help you.
What Mikrotik device are you using?
Which version of Router OS runs on it?
How does your network setup look like?
