Cannot login to Crystal Data Centre

Hi there, I've been playing without issue most of the day when a random DC started this issue.
I've not been able to get back onto any character on Crystal.
Error codes so far have been 2002, 90006, 1014.

I can log on to characters on other data centres without issue and even managed to get one character from Crystal over to Dynamis but on trying to get them back to Crystal it all started up again.

So far I have reset the router and checked firewalls, permissions, but no luck, my internet connection seems to be working perfectly fine

I'm not too hot on the techy side of things so I apologise in advance for being dumb, but any help would be amazing! Thank you.

(Edit: Just to add it seems to be any server on Crystal where Im having this issue)
