Server Version#: 1.43.3.10896 Player Version#: 4.160.0 [app.plex.tv](http://app.plex.tv) is unable to connect to “Server” securely. After restarting the server, clients on phone and TV stopped connecting, they all report that libraries are unavailable because the server is offline, yet everything works fine when accessing it from a computer via the local address. I found the following in the logs: "Sep 05, 2026 21:18:46.137 [140304870251320] ERROR - CERT: Error acquiring new certificate: Failed to upload CSR: 429, ". As far as I can tell, this is a block imposed by Plex. Could you tell me how to fix this issue? ---

For several weeks now, your server has requested new certificates – sometimes several on a single day. This leads to rate limiting. Stop Plex server. Make sure that your whole [Plex data folder](https://support.plex.tv/articles/202915258-where-is-the-plex-media-server-data-directory-located/) is fully accessible to Plex server – with both “read” and “write” permissions. Locate the file `cert-v2.p12`in the `Cache` subfolder and delete it. Please report once you did this. Please do not start Plex server in the meantime. ---

The server has been stopped, the certificate has been deleted, and the ‘Certificates’ folder within the Plex directory has been set to 755 permissions. ---

Please try and start your server. Let it sit for a few minutes. ---

It should have gotten a new certificte. Has the `cert-v2.p12` file been recreated? ---
