Error 520 - Administration » Settings

Hello,

After trying to update the configuration within: Administration » Settings

I am receiving the following error:

Nothing is saved and I am stuck with the same settings. Please find my system requirements below:

I am working with version 5.6.3. I have tried clearing cache and rebuilding several times but the same '520 Error' keeps occurring. Any ideas on how to remedy this situation would be much appreciated.

Hello.
This error returns by your server. Please check it error logs.

Thank you Maximus. I believe that even though I was given green check marks confirming proper settings during the installation process; I am going to have to tweak certain areas on my server. I have referenced similar situations such as 520 errors arising due to NGINX with Apache handlers. My server environment is setup to use NGINX with Apache. Again, I thank you for your time and support.
