CERT: Error acquiring new certificate: Failed to upload CSR: 429,

Plex Media Server Remote Access
1

Server Version#: 1.42.2.10156
Player Version#: 2025.30.0 Android
Having issues with my plex server. For some time now I have not been able to use my Android client to access my library. I have setup remote access and it says that it is not reachable on the port. However, if I connect to my public IP address with the port I can access my Plex library.

Thinking that my problem is my equipment I have done the following:

  1. Upgraded Debian to the latest versions.
  2. Added server: private-domain: “plex.direct” in appropriate formatting to my pfsense box. (Which it was working before without this)
  3. Left the server powered off for a couple of hours and then back on.
  4. Cleared all storage from my Android Plex app and re-signed in.

Any other thoughts?

I am also seeing in the logs:

I reset the certificate

While there, you had two other machines which hadn’t been active in years.
I removed them for you.

You may restart the server

Thank you. I just rebooted and everything is back online.
