Mac server just spins on launch

Plex Media Server Desktops & Laptops
1

I paid for plex plus,downloaded the mac media server and double clicked. I get a browser window with a spinner that never stops. What are my next steps? Mac powerbook with 8 megs of memory running 10.15.7. I wasn’t hoping to become a full blown sys admin just to watch OTA tv outside my home. The browser shows: http://127.0.0.1:32400/web/index.html#!/client-setup. Do I need to enable something for the app to talk to Safari?

Here’s the console output:

Do you get the same issue using a different browser or after disabling browser add-ons / blockers?

3

Yep, Chrome does the same thing.

4

Any “security” or content/add blocking apps that could interfere with Plex properly connecting?
Would you mind sharing your server logs to see if there’s any server-side issues?

It started working. I rebooted, logged back into plex and re-downloaded the media server. Something in that fixed things. I’m running on Chrome. Not sure if Safari works or not. But as long as I can get it going with Chrome, I’m happy. Thanks for your advice.
