How to renew our Let's Encrypt certificates v-update-letsencrypt-ssl

I see the following error:

Error: Let’s Encrypt validation status 400 (ZZZ.XXX.YYY). Details: 400:“During secondary validation: 000.000.000.000: Fetching http://ZZZ.XXX.YYY/.well-known/acme-challenge/EEEEEEEEEEEEEEEEEEEEEEEEEEEE: Timeout during connect (likely firewall problem)”

how can I solve that? Thank you

Try it again. Try to access the url from your computer or provide more information…

I get the error email because it is when the following cron is executed.

Cron [email protected] sudo /usr/local/hestia/bin/v-update-letsencrypt-ssl

If you need more information you can tell me which one, thanks

I have solved it by putting the CSF in TESTING mode ON and I have executed through SSH the v-update-letsencrypt-ssl
