Hi @sircollins
read your error message. Your elearning.taalct.co.za has the wrong certificate, it’s with the name shop.taalct.co.za.
But checking your domain you have created a new certificate - https://check-your-website.server-daten.de/?q=elearning.taalct.co.za#ct-logs
| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |
|---|---|---|---|---|---|
| Let’s Encrypt Authority X3 | 2020-01-25 | 2020-04-24 | elearning.taalct.co.za - 1 entries |
So it’s only an installation problem. Install the certificate you have created.
