No outputs Today - Api key error

I’ve never had any problems with PvOutput outputs, mostly it’s Solardedge that is not uploading.
But from today, and for the first time ever, there is no output for today.

How can i troubleshoot this in my settings?

system link which shows nothing for the 24th

edit: maybe this helps. when testing the API key;

HTTP Status 500 – Internal Server Error

Type Status Report

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Apache Tomcat/8.5.46

edít 2: now I am receiving a csv file with some data, but still no outputs. This annoys me :stuck_out_tongue:

This isn’t a PVOutput error…
