LiveBook Proxy url does not work

[hpoiters]

Describe the issue

I use Fritz19 and Playchess for online computerplay. If i disable all books, exept LiveBook Proxy url
http://www.chessdb.cn/cdb.php?action=querybest&learn=1
The live book is not used. I see nnue counting at start of 1st move. (depth is set to default 255)
In ShashChess, the iveBook url is working good, only not in Brainlearn29 x512

Expected behavior

I expected that livebook connection would give immediately moves, without counting for best nnue move, as far as the depth is set.

Steps to reproduce

Anything else?

Operating system

Windows

Brainlearn version

Brainlearn 29 /8ff4ee3

But do you have the proxy?

If I change engine to ShashChess, and use the same url:

http://www.chessdb.cn/cdb.php?action=querybest&learn=1
All works fine. It is only with Brainlearn that the url is not working, and/or does not contact the server.
If I use Brainlearn and the livebook from Playchess, it works 1 time, and the next game it is shutoff. It seems the livebook server from Playchess is often off-line. That of chessdb.cn is alway working, exept not in Brainlearn.

ShashChess
Experience book is used first, thereafter the database url gets moves.
If I shut off Experience, only the livebook gives the opening moves.

It seems to me that with the Santiago version, the problem of not working LiveBook url is solved. Thanks.
