My Railway PHP workers (with infinity loop) lose MySQL auth after ~20 min; same root creds fail with 1045 as internal IPv6 host changes.

{ "where": "runFromIndex", "error": "SQLSTATE[HY000] [1045] Access denied for user 'root'@'fd12:e6a2:5c4e:1:2000:1d:e8b5:de8d' (using password: YES) (Connection: default, SQL: select * from automation_steps where automation_id = 35 order by step_order asc)" }

Any help? Thanks.
