Server Version#: 1.43.1.10576
Player Version#: NA
I was updating my QA plex instance container to test the new public server version.
I don’t start this instance often; I think Sep 2025 was the last time i tested it. As such, my ssl certificate was expired, but it would not renew, throwing a 502 error.
I initially started the instance with its previous version (1.42.2.10156) before upgrading, it threw the same errors on that version as it is now on the current version.
