Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
vconf.dns.cloud.net
I ran this command:
/usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh
It produced this output:
This script will:
- Need a working DNS record pointing to this machine(for domain vconf.dns-cloud.net)
- Download certbot-auto from https://dl.eff.org to /usr/local/sbin
- Install additional dependencies in order to request Letās Encrypt certificate
- If running with jetty serving web content, will stop Jitsi Videobridge
- Configure and reload nginx or apache2, whichever is used
