Remote access suddenly broken - certificate error

Server Version#: 1.32.5.7210 Unraid docker)

(Full disclosure: also posted this here last night but haven’t seen a response, so I figured I’d try this forum as well: Plex Employee to Reset Server Certificate? "API rate limit exceeded" error - #533 by ChuckPa)

Remote access has been working well for months, but it seems that after a recent container update, I’m getting a rate limit error getting a cert:
Jul 06, 2023 18:32:57.543 [23404873997112] ERROR - [Req#a6] CERT: Error acquiring new certificate: Failed to upload CSR: 429, <?xml version="1.0" encoding="UTF-8"?>

Is this something that I can reset, or do I need someone from Plex to do so? Would like to get things working for this weekend if possible. Thanks in advance!
