Pointing out in case site manager is unaware…appears the cert is expired
Yeah they should look into it.
As its hosted on a Plesk Server and ‘secured’ with a Let’s Encrypt v3 Cert it should not be a lot of work to renew the Certificate.
Also I would recommend them to Auto-ReNew the Certificate, so this will not happen again.
@crafter maybe you can do this, as visiting the Main-Page triggers a warning.
