Content Server and Marvin 3 Not Working

RedCanyoneer · 04-08-2020, 04:28 PM

Marvin 3 (3.1.2 Build 34) is not finding the Calibre (4.13) OPDS Content Server.

I start the content server on Calibre on my PC (Windoze 10 latest). It shows it as running (10.0.0.8:8080, the port varies sometimes, and the IP varies depending on what IP the computer boots to, obviously).

In Marvin (iPhone X, iOS 13.4.1), I click "OPDS Auto or calibre server". "Searching" appears, but never finds a content server.

If I fire up my browser on the iPhone (Safari) and manually go to 10.0.0.8:8080, it shows the Calibre library. So it's not a firewall issue on my PC.

In the past, updating Calibre (if required) and rebooting has fixed this. But that's not the case now. When I did connect successfully in the past, Marvin would find Calibre almost instantly.

All my books (well, most of them) are DRM-free ePubs. A handful are PDFs.

I'd really like to be able to connect to OPDS Auto from Marvin 3, as it's a really easy way to grab my books. Thoughts?

If you can access it via browser, the server is working. Beyond that you will need to ask the developer of marvin for debugging help.

OK, you're going to hate me. I tried something else. UPDATE: Fixed but I'm not sure why.

I have another computer - an old laptop - laying around. I installed Calibre on the laptop, fired up the content server, and both of my iDevices saw it immediately.

Older Lenovo Thinkpad, but running Windoze 10 latest, 10.0.0.16:8080, near as I can figure all network and firewall settings are the same. So I concluded not a problem with Marvin.

From each PC, if I use Chrome to browse the Calibre library, I can see the library on the other PC.

So, on my main PC, I uninstalled Calibre. Then I used CCleaner to look for orphaned registry values. I deleted both the Calibre program and Calibre-related firewall entries. Re-installed Calibre. When starting the content server, I got the allow firewall access message. I allowed for both private and public networks. Used Marvin on the iDevices to look, and I saw the content servers for both PCs. Solved for now, but like I said, I'm not sure why.

So, related question, if this happens again: is there a way to completely uninstall Calibre? I'm guessing I didn't get everything in my uninstall, as Calibre found my old library - I would have expected it to ask where or create a new one, as it's in a non-default location.

Thanks again!
