The TCP trace looks like the client side is timing out too quickly in the unsuccessful case. It's not clear to me how the different Discourse version would lead to the Kerberos library applying a different timeout. Still, it seems like most of the moving parts here are outside of Postgres' control --- I don't think that libpq itself has much involvement in the KDC communication. I concur with looking at the Discourse release notes and maybe asking some questions in that community. regards, tom lane
