Solution:
Go to Central Administration > Application Management > Manage services on server > Sharepoint Server Search and set it to ignore SSL warnings. Repeat full crawl of your content source again.
Or in powershell:
$searchService = Get-SPEnterpriseSearchService
if($searchService.IgnoreSSLWarnings -eq $false)
{
Write-Host "3. Setting Ignore SSL Warnings to true..." -NoNewline
$searchService.IgnoreSSLWarnings = $true
Write-Host "OK"
}
