Unable to connect to Plex to retrieve app.plex.tv certificate

[jber790]

Server Version#: 1.29.0.6244
Player Version#: NA
I am seeing the following error in my PMS Console output AFTER I cleared the Config/Cache directory and restarted Plex Media Server (I did this because I saw the same error and attempted to resolve by clearing cache and restarting PMS):

CERT: Error acquiring new certificate: Failed to upload CSR: 429, <?xml version="1.0" encoding="UTF-8"?> <errors> <error code="1003" message="API rate limit exceeded" status="429"/> </errors>

Reading other forum posts, do I just need a new cert. issued by Plex?

Thank you.

@ChuckPa - can you assist with resetting my certificate to help resolve this?
Thank you!

It appears (possibly) this issue started occurring on Oct 16 and while the cert. was downloaded successfully here:

It failed to downloaded when I restart my PMS nightly (1:15 AM PST):

Oct 16, 2022 01:15:28.145 [0xaf441c50] ERROR - CERT: Error acquiring new certificate: Failed to retrieve cert from plex.tv: 429, 

but then appears to have successfully downloaded it 9 hours later:

https://plex.tv/api/v2/devices/f7578a5a918bdfb2e2c456c5d117169485f8083d/certificate/download (reused)
Oct 16, 2022 10:36:06.623 [0xae50cc50] DEBUG - CERT: Downloaded new cert from plex.tv; took 11 tries.

Is this an intermittent communication issue with plex.tv that is causing this? Currently I am getting the

CERT: Error acquiring new certificate: Failed to upload CSR: 429, <?xml version="1.0" encoding="UTF-8"?> <errors> <error code="1003" message="API rate limit exceeded" status="429"/> </errors

and I am still unable to connect my server to app.plex.tv and use other Plex apps. in the same way (my PMS is unavailable). I can connect to and administer the PMS on its insecure LAN IP.

Thanks.
