I noticed that my cert is not valid anymore (despite i set automatic renewal in crontab), so i tried to renew/recreate the certificate manually and i got this error:
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org An unexpected error occurred: ClientError: <Response >
It seems that acme-v01.api.letsencrypt.org is not working right now. Any hint to fix this? Thanks.
