After trying it has something about OpenSSL, I think the app compiled with an old version of OpenSSL.
[Edit]
I compiled it from source and the downloading working good but the browsing part is not working
If you want to compile it from source
sudo eopkg it -c system.devel
sudo eopkg install qt5-base-devel qt5-webengine-devel
cd ~/Downloads
wget https://download.clipgrab.org/clipgrab-3.8.12.tar.gz
tar -xf clipgrab-3.8.0.tar.gz
cd clipgrab-3.8.0
qmake clipgrab.pro && make
./clipgrab
