Cannot get a cert (429) on a newly restored Plex Server (windows)

Server Version#: 1.43.0.10492
Player Version#:

Yesterday the system drive on my windows plex server died. Today I got a new drive and installed windows fresh. I still had my plex settings folder because I previously relocated it from appdata to another drive. I successfully pointed a brand new plex server installation to use those settings, and I have my libraries back.

Remote access is working “Fully accessible outside your network”, as I made sure the port forwarding config is good. However, I cannot access the server outside of the local machine, and I can see locally that there is no cert. I found the cert error in the logs, and they were requesting a cert for UUID 8adc5ba76e087a136a12669618736cb0eba91c56, and my old preferences had an old MachineIdentifier guid (MachineIdentifier=“61487dcb-8d9a-4dd5-8df9-e2f43890a051”), so after some research I tried replacing that MachineIdentifier to the new UUID.

Still no cert, and looking at the logs, I’m getting throttled with 429s. I have been restarting my server a lot today to try and get it running, so that may be why. Can I get some help unblocking this? Thanks.
