Fail in installing step

[baoyl818]

Hi, friend

when I install the software, it errors as this :

Scanning dependencies of target seqan
[  5%] Creating directories for 'seqan'
[ 10%] Performing download step (git clone) for 'seqan'
Cloning into 'seqan'...
error: RPC failed; result=18, HTTP code = 200

CMake Error at /../neusomatic/third_party/seqan/tmp/seqan-gitclone.cmake:66 (message):
Failed to clone repository: 'https://github.com/seqan/seqan.git'


make[2]: *** [/../neusomatic/third_party/seqan/src/seqan-stamp/seqan-download] Error 1
make[1]: *** [CMakeFiles/seqan.dir/all] Error 2
make: *** [all] Error 2

Does it mean that my cluster can not connnect to the 'seqan' github ？ I have already installed the depened softwares and python packages.

Thanks
