.btsearch isn't been loaded - uTorrent 3.5.4.44520

[emc]

Hi.

After few years I created new .btsearch plugins. But it seems to uTorrent has a bug.
.btsearch isn't been loaded to uTorrent 3.5.4.44520.
Known problem in old versions of uTorrent - .btsearch with https doesn't work. But http works as well.
I am not able to do it working on actual version of uTorrent.

Additional info:
untill 3.4.7.42330 still OK (https never)
since 3.4.8.42548 no longer
