Error 630 when trying to login to old pso2

I have been away from the pso2 base game since Sep last year, and recently back for NGS. Been trying to login to old pso2 since NGS launch but always 630 error. Never have any connection issue with NGS though. Btw i started on xbox windows but only play on steam after pso2 available on steam. What could be the reason with this error? I tried different ways to fix it but no luck.error 630.jpg

Same problem here. No matter what time i try to do that. When NGS dropped i cant visit PSO2. Well, devs cant do anything about this error bc i saw same problems in past few yers 😛
