Hi, I’m in the process of putting together a new Plex server and apparently it’s hit a rate limit for grabbing the SSL cert? I disabled wan access for Plex for just over 12 hours, but still received the same error again when reconnected. Do I need to wait longer or is something else going on? Thankyou!

I looked at Plex.tv.

Your server’s certificate got stuck in generation.

You were getting the 429 for the CSR because another was already processing.

I cleared the existing. It has now created a new one.

Please restart the server.

Hey, ChuckPa! Is there any way you could reset my cert also? I am having the same exact issue as shown in the console log above.

Cleared. Please wait 10 minutes, then stop and restart Plex server.
