Migration from Certbot

Recently, our Certbot began to throw inexplicable errors, and I was told that it is no longer supported on Windows, so I installed CertifyTheWeb client. It immediately picked up our domain, not sure how, and showed the correct number of days until expiration, which is nice.
When I click on Renew All, it switches to a blank tab:


There is no progress indicator, so I am not sure what is going on, is it doing anything, or how long to wait for the renewal to occur. Is anything amiss?

Hi,

The app can monitor certificate status for some other ACME clients like Cerbot. It will says something like “Managed by Certbot” when you click the managed certificate details.

As you are a certbot user I would guess that your web server is apache or nginx, please see our general guide here: Using with Apache, nginx or Other Web Servers | Certify The Web Docs

I would recommend using DNS domain validation instead of HTTP domain validation if you can, as otherwise you need to configure how your web server will answer the HTTP challenge etc.
