After moving from a 14” Macbook Pro with an earlier version of MacOS to another Macbook Pro running the latest version of the MacOS, I began having trouble with the Calibre content server. Previously, I was able to access my Calibre (7.12.0) library (“Master 3 Calibre”) using the last version of Marvin running on an iPad client. The library was stored on a 4 TB external SSD connected directly to my Macbook Pro via a USB 3.0 port. The iPad and the 14” Macbook were both connected to my home Wifi.

After cracking the screen of the 14” Macbook Pro I used Apple’s Migration Assistant to move into a new 16” Macbook Pro running MacOS Sonoma 14.5 (Apple upgraded the older 14” Macbook Pro OS to Sonoma during the repair). The Calibre library is still on the same 4 TB external SSD connected directly to the (new 16” Macbook Pro via a USB 3.0 port. I can access the library and its contents from within Calibre. But now I can no longer access the library via Marvin using the same iPad client with the same configuration as in paragraph 1. There have been no changes to the home Wifi during this period.

When I try to access http://127.0.0.1:8080 from the 16” Macbook Pro using either Firefox or Chrome I get one of two messages (#1 is most common):

1) Failed to communicate with "/interface-data/init?1718818376536", with status: [404 (error)] Not Found
Library 'Master_Calibre' not found (note: my library on the SSD is called: “Master 3 Calibre”)
2) Failed to communicate with "/interface-data/init?1718821160179", with status: [500 (error)] Internal Server Error

I’ve tried the following:
1) I’ve toggled stop/start content server in the “Connect/share” menu several times. No change.
2) Doing the above after restarting the 16” MacbookPro in safe mode. No change.
3) Doing the above after reverting to a 6.x version of Calibre. No change.
4) Doing the above after switching to an older version of my library located on the 16” MacbookPro’s internal hard drive. No change.
5) The 16” MacbookPro’s firewall is configured to allow incoming connections to Calibre. Even so, I’ve tried turning off the firewall of the 16” MacbookPro. No change.
6) I’ve switched from auto to basic authentication in the server settings under advanced and restarted Calibre. No change.

I’d welcome suggestions.
