GT7 Error code CE-210381

[FBR_MikeB]

I've done port forwarding to open up the connection to my PS4 but that didn't make any difference for this error code. Does anyone know or had a similar problem? any help would be appreciated. Thank you.

Have you tried connecting to an empty lobby?

Personally I've never been able to connect to a lobby with other players in it. I assume that lobbies are player hosted (not on PDs servers), which would exacerbate connection issues. I haven't tried this yet, but if you can join an empty lobby with no issues, it may be indicative of a P2P issue.
