Login issues for NFS Most Wanted Vita Version

Hi there, since i am using Playstation Vita i recently bought NFS Most wanted game and tried to play multiplayer which i am not as i keep getting an error saying "CONNECTION FAILED" no matter. Been trying since 4 days but no luck. Tried every method from internet by delinking my account from EA website and linking back again then uninstalling the game and reinstalling. Even tried starting a new EA game in PS5 and Logging in which worked fine. Other games are able to connect to net except NFS Most Wanted in my Playstation Vita. Please do me a favour by helping from this bug. Hoping to get a response as soon as possible.
