What on earth is going on?

Hi Folks, I have a couple of questions.

I cannot sync anything from my server to the local computer. Getting an error of service unavailable. Have attached some screens.

I have added the required text to the php.ini file at the bottom and restarted the service. No dice… What am I doing wrong?

Permissions are 750 on the next cloud folder.

Would appreciate anything that anyone can offer…

Here is some text from the log:

Can you output the apache error log as well please?

Hello did you get rid of this error?
I get the same issue here and I don’t understand why…
