Alien.py not working

I have installed my grid certificates on a globus folder both in lxplus and on my laptop, I have build O2Physics and I have checked that my certificates are working on VOMS, yet, when I am on the O2Physics environment and I try to run alien.py in the globus folder, it displays the following message:

Enter PEM pass phrase:
Invalid status code 401 connecting to 137.138.99.147:8097
InvalidStatusCode(401, Headers([(‘Cache-Control’, ‘private’), (‘vary’, ‘accept-encoding’), (‘Content-Type’, ‘text/html;charset=utf-8’), (‘Content-Language’, ‘en’), (‘Content-Length’, ‘740’), (‘Date’, ‘Tue, 04 Jul 2023 12:28:43 GMT’)]))
Check the logfile: /home/narcio/alien_py.log
The status code indicate that your certificate is not authorized.
