The apache stopped to work, si I had to reset it using the vitalpbx -reset-apache-conf. And everything started to work again. Later I go to the config to reissue the certificate but the system reports that the cerficiate already exist. I deleted the folder of the certificate but nothing, the system still says It’s registered.
Yes, I have indeed deleted the previous certificate (thank you) and generated a new one, but it does not install it, although it does not seem to give an error, in the browsers it still shows “unsafe site”. The date, as you can see in the image, appears wrong.
