PSN users are confirming problems with the use of PS4 core services tonight.
PlayStation players report problems using the party system in most games, including Apex Legends.
It is not clear what is causing the problems of tonight or how long the current interruption may last.
Error messages displayed by PlayStation Network users include warnings about connecting to part chats.
"You have been disconnected from the party due to a network error," reads a message.
The good news is that reports on an interruption are decreasing, which means that problems with PSN core services may not last long.
Reports tonight are limited to users, with no update currently available from Sony PlayStation on the subject.
UPDATE: Sony PlayStation has now released an update on current server issues, which has confirmed that it affects games and social services.
This includes playing online PS4 games, as well as other online services.
"You may have some difficulty launching games, applications or online features," says a new statement from Sony PlayStation.
"Our engineers are working to solve the problem as soon as possible and we thank you for your patience."
