Https certificate problem

I have a load balancer with a public VIP. The partner can only get the site if they ignore that they perceive the site as unsafe.
I’m fairly the certain my very is valid because other VIPs use it. What are some reasons a client might not trust the cert? Brain storming question.

Just check out what the cert says, and compare that to your host.

If eg your host is www.domain.tld and the cert is just for domain.tld you need to create the right cert.
Other potential reasons are that if the cert was produced by an internal root authority rather than a publicly verified CA, the machine may not trust the CA.

Or it could be as simple as the machines time being incorrect which might make it think that the cert is expired/invalid.

If you use a Load Balancer, then you'll have to setup your DNS to reference all Load Balancer IPs as A records for your domain.

Then you'll have to somehow associate your SSL cert with each Load Balancer instance.

This type of config depends on your runtime environment.

Open a support ticket with the company maintaining your Load Balancers + likely they can quickly walk you through this setup.

Note: Load Balancers are rarely required. Better to hire someone to tune your LAMP Stack to run at blazing fast speed, so there's no requirement for load balancers, CDNS, proxies (NGINX/Varnish/Squid) or any other cruft technology between Apache + your visitors.
