Auto renew of certification fail

1

Hi,
Few of my applications are are not identifying the certificates after 30th September.
When I verify the certificates are still valid. But our applications are not able to communicate with other applications.
For example we use to connect a api in one of our dashboard application and we get the below error on connection

Processing: dashboard error.html…

I tried a dry run on certbot and I get the failure message for my application certification.

It sounds like you are using Certbot, not Certify The Web, if so you may be able to get better help in the Let’s Encrypt forum: https://community.letsencrypt.org/

In general though, you need to make sure your server software is update to date and that you have all the latest CA certificates installed in your operating system (is this a version of linux?).
