The host has the name zeus.XXX.com and the domain under which OsClass runs is prod.XXX.com. All on the same host. Why doesn't it work with the API key?

Hello
Could someone please help here?
Thank you very much.
Greetings

Try to enable allow furl open setting

Unfortunately, that is not the problem. Was enabled.

allow_url_fopen = On

Probably not able to help, there is something wrong with your host/localhost as I never seen these issues before...
Can you send error related to that host like full with tracing where it starts?

What is interesting is that everything works completely clean so far except the API key.  The system is completely new. OsClass is still in the default state.

It would be great if someone could explain to me how the process works, because I can't figure it out from the logs. This would have to be looked at by someone who wrote the code.
