Unable to change settings

Hello there,

Every time I try I press “Save plugin settings” in the Settings area of the plugin, regardless as to whether I actually make a change or not, I constantly receive a connection error in all browsers and all possible networks that are available to me.

My hosting provider has confirmed that they monitored the packets when I recreated the error and none of them were considered to be under any blocked rulesets. If it’s any consolation my server is using PHP 5.4 and my provider is Krystal.

Here is a video of me recreating the error:
