Thanks for the reply. You have written some fantastic software here, and are extremely quick and helpful in addressing questions. I wish all people I interacted with were as good as you!

That's what I've been doing. But I found a bug in that route. Which is what made me start investigating hitting the main Content Server webpage and not a library bookmark.

The first time you access the Content Server using a bookmark to the library page, before the Content server has had any chance to store its local data in your browser, you get the login/password popup. You authenticate, and it puts you right on the library page that I want. Expected operation. After authenticating, I told the browser (Chromium version 62) to remember my password.

Then I exited the browser and did the exact same thing again. The login/password popup hit the screen for about 1/2 second, then automatically dismissed itself, then I got a "401 unauthorized" message from the Content Server. This is unexpected behavior. In the brief 1/2 second that the login/password popup appears, I can see that my saved login information is being displayed. the bad operation appears as if the login/password popup is being populated, but then immediately canceled rather than being submitted.

Additional info: When this behavior begins, if I keep clicking on the same library bookmark over and over, somewhere between the 4th and 6th click - it lets me in normally! I and not changing anything in my process, just clicking the bookmark repeatedly, and finally it works. [ I know, "Doing the same thing over and over and expecting a different result is the definition of insanity." But in this case, it worked! ]

More info: If, after this behavior begins, I go into Chromium settings and manually delete all of Calibre's locally stored data, then try the bookmark again, then it works fine this way too.

Yet more info: I cannot duplicate this behavior in Firefox (version 57). That browser works perfectly every time when using a bookmark directly to the library. So my initial guess is that this is some interaction between Chromium and locally stored data and authentication. I can't say this for sure, but that's the way it appears. If I turn off user authentication, then everything works fine.

Here is the error that I get:

Code:

Failed to load books from calibre library, with error:
Failed to communicate with "/calibre/interface-data/books-init?library_id=Calibre&sort=author_sort.asc%2Cseries.asc&1511363334946", with status: [401] Unauthorized

And here is the bookmark that I am using:

Code:

http://10.192.0.26/calibre/#library_id=Calibre&panel=book_list&sort=author_sort.asc,series.as

I have found through my testing that I have to include "library_id=Calibre" in the bookmarked URL. however, I do NOT need to include the "vl=Novels" part, as that seems to be handled by the user definition in Calibre (shown above, in my initial post).
