Hi, Contact amazon support team also and they replied me like below :
"Yes, while I was accessing the website 'https://marketing.funding4education.co.uk/ ' I got the mentioned error. I think yesterday's problem was due to syntax errors in Bitnami HTTPD Configuration, please correct me if I am wrong.
As per the screenshot provided by you, the SSL warning is being raised by Kaspersky Antivirus. Please refer. When I try to access the website today, I am able to see the 'Mautic Login Screene', but with a warning "Your connection to this site is not secure". I am attaching a screenshot for your reference.
As you have contacted Bitnami Support, I think you can resolve the SSL issue. In case if you are still not able to resolve the problem, I will try to help you on a best effort basis."
So, there is ssl issue please confirm this and provide solution for that.
