Server Version#: TrueNAS 12.0 U4, Jail version FreeBSD 12.2 U8
Player Version#: 1.23.2.4625
Upgrading to 1.23.2.4625 causes me to irrevocably lose access to server settings (none of the generic advice to recover from this works).
I also attempted a fresh install of 1.23.2.4625 in another jail. This attempt fails to start with a generic error. So I don’t believe my configuration is the problem.
Both the upgrade attempt and the fresh install were done via “pkg”.
Based on this post I just found, I strongly suspect this issue first surfaced in the 1.23.0.4459 beta and was never resolved. The workaround described in there should really be part of the package. In the meantime, I’ve already downgraded to 1.22.3.4392.
