I am facing the following issue: I manage a WordPress website (https://mhm.nl), with an installed SSL certificated. I recently changed the website domain from https://mhm-og.nl to https://mhm.nl, since then the website cannot be accessed from Safari or Internet Explorer anymore, whereas it works perfectly in Chrome (and apparently also in Firefox). The error Safari gives is: "can't establish a secure connection".
I checked several tools like why no padlock, test SSL etc., but everything seems to be configured properly. I also cleared all the caches a hundres times, but this doesn't solve the issue.
Web server: Apache/2
The operating system my web server runs on is (include version): Linux 3.10.0-962.3.2.lve1.5.28.el7.x86_64 x86_64
My hosting provider, if applicable, is: Transip
I can login to a root shell on my machine: Yes
I’m using a control panel to manage my site: No
The version of my client: N/A (I think, because I HTTPS is built in)
Does anyone have an idea what this issue could be? If you need any more information, please let me know!
