pip3 install failed due to an EnvironmentError

I'm trying to install imutils and dlib via pip on my 64 bit ARMV8 board. pip3 install imutils throws certificate verify failed error. I now have to use pip3 install imutils --trusted-host pypi.org --trusted-host files.pythonhosted.org to bypass that certificate error. It was working fine earlier, but suddenly it started giving this error. How can i fix this instead of writing --trusted-host everytime? ERROR:
