Could not login to custom OPDS catalog (basic auth)

[blacklion]

I've installed my private OPDS catalog, and try to use FBReader (desktop, 0.12.10) to access it.

I added file to "share\FBReader\network" with description of my catalog. It requires HTTP basic authentication.

When I click "Open catalog" I see request to serve (via web server log file) without auth. And, of course, FBReader shows: "Network error / Something goes wrong for ". It is expected, as I don't provide login/passwrod.

Ok, I click "sign in" and fill username/password. After that NO requests is seen by server and FBreader shows "Something goes wrong for " immediately. So, I could not sign-in into mm catalog.
