I started getting Error 630 disconnects about a month ago after 6 months away from home. Prior to that I had been playing PSO2 since it came out on Windows Store then transferred to Steam, so over a year of playing without issues on the same system, same ISP, same router, etc. I've tried to find solutions for it but have not had much success with anything provided in other threads including port-forwarding, running as administrator, and more.
I was hoping that with the NGS drop the problem might have fixed itself (even though it's the same servers, you never know), and managed to get through the prologue with a new character. I then decided to log out and re-customize my PSO2 character and play through with her instead, and got Error 630 three times mid-customization in about 10-15 minutes.
I really want to play this game and was very excited, but this is a gamebreaking issue. I would really appreciate any assistance and possible solutions, even if it's stuff that I've tried already. If something worked for you to fix 630 messages, please tell me and I'll try it.
