I have a annoying problem on my website. I've installed a wildcard certificate today, which seems to work fine.
The browser does accept the certificate and my website is safe. But sometimes when I'm using my website, the certificate isn't valid anymore. And then when I refresh it suddenly is.
Does anyone knows where to start searching?
I'm using DirectAdmin. I've used Let's Encrypt and a Wildcard certificate from Sertigo.
Website is kolaber.com, and every subdomain (*.kolaber.com) should be safe.
