My hosting company (misshosting.com) had some down time today. I don’t know if it was some hacker attack, but all my sites including their own was down for several hours. When it came back up, all my sites were functioning nomally except one. When trying to access it, the web browser warns me that the site is not secure and that it was not possible to identify the certificate. I could continue to the site but the green lock icon in the adress field was gone and now it’s a red cross saying that the site is insecure.
It also says that my let’s encrypt certificate expired in august, but that’s not true. I checked it in Cpanel and it was renewed in August and expires in December. So somehow, it seems that the downtime of the hosting company screwed something up. Any ideas how to fix this? I already tried to reinstall the certificate and also to issue a new one, but it didn’t help.
