https://repo.reindexer.io responds with certificate has expired

I'm trying to install Reindexer from the repo.reindexer.io, it seems that SSL certificate has expired, and https://repo.reindexer.io cannot be reached.

Log output:

curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
gpg: no valid OpenPGP data found.
Error: Process completed with exit code 2.

Could you update the SSL certificate for the given repo, or provide a new one with a valid certificate and reflect it in the documentation.

Thanks.
