Rekey of letsencrypt

I am currently operating a jitsi server.
I got the certificate with letsencrypt before installing jitsi.
I tried to rekey for the first time because letsencrypt’s 3 months expired, but it didn’t work.
I’ve verified that the jitsi server is receiving HTTP queries from the internet for verification, but the jitsi server is returning an error.

I contacted the Letsencrypt Community and they recommended a root location of /var/www/html.
But the root location has been rewritten by jitsi to /usr/share/jitsi-meet.
How can I update the key in this situation?

I’m not sure I understand the issue correctly but if the root location is the issue and if this server hosts only jitsi you may link /var/www/html to jitsi home.

mv /var/www/html /var/www/html.old
ln -s /usr/share/jitsi-meet /var/www/html

By default with old code that manages let’s encrypt a cron job is installed that should take care of the renew.
With the new one ( it is also managed internally and renewed when needed.

Thanks for your comments.
Key update was successful by changing the webroot.
I’ve been struggling with this for the past week.
This time, I got the certificate while the root was /var/www/html.
After that, the root was switched by installing jitsi, but letsencrypt tried to renew without knowing this.

This sounds like some miss configuration in the web part.
