Failed renew ssl pritunl dashboard

Hi, I have an issue with SSL update failure, even though the dashboard stated that SSL renewal will be done automatically, why did it not happen automatically? And now it has already expired. In the log, there is information about the failed renewal. What is the solution?

FYI, i use pritunl enterprise

The Lets Encrypt servers require port 80 HTTP access to the Pritunl web server at the IP address registered to the domain.
