It looks to me like you just added your site to Cloudflare, so you probably checked while a certificate was still being issued. The CT logs show Cloudflare starting to generate a certificate for your site yesterday at 2020-06-09 18:16:31 UTC (https://crt.sh/?q=fgx.co.za). In the few minutes I have being looking a new pair of precertificates have appeared, so perhaps you turned a few things off and on (like SSL Mode and/or Universal SSL) while waiting for the certs to be issued.
I can see a valid certificate for your domain being returned by Cloudflares edge now, so can you confirm that this issue is gone away?
