The certificate has always worked.
But now is also the problem when I type https I go to an other site. Hosted on the same vps with an ssl cert.
hmm, you should reach the right site anyway, the ssl status does not matter. so it seems to be a problem with the configuration. do you have any direct modification inside of the nginx/apache2 conf files? If not, try to disable ssl, then rebuild user (v-rebuild-user username), reenable ssl (create a selfsigned cert), then check if you can access your site. if this works, disable ssl again, then reenable ssl with checking the let's encrypt box. No warranty that this will help, there is also the option that the problem will be bigger because the user rebuild.
