问题
I created a Google application in the developers console, turned on "YouTube Data API v3", generated the server API key, and authorized my home and work IPs.
My website lists all videos from a Youtube channel, using the V3 API. It uses the official PHP library, passing it the server API key.
It all worked well yesterday from home, and today morning from work. Then, it suddently stoped working at 11am (GMT+1), with no action from my part, with this error:
[Google_Service_Exception] Error calling GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=xxxxxxxxxx&key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx: (403) Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your APIkey and the request does not match these restrictions. Please use the Google Developers Console to update your configuration.
Note: i used less than 10 requests, out of the 50 millions allowed by day, i have a static public IP address, this part of the code was untouched.
What can i look for in order to fix that, please? I really don't know where to head for from now... Thank you.

Oooook...
Do all you have to with the API activations before you generate any keys!
Unactivating or reactivating API (like "Youtube Data") silently destroys your key validity. At least for the server one.
So the solution is, when you get the same error as me:
- destroy your server key (delete it completely, do not only regenerate)
- deactivate then reactivate all APIs you need
- create a new server key
- thank Google for the so clear error messages (optional)

This solved for me.... i first followed @Ninj answer...still no change. Then, After adding my domain urls to 'allowed referers' list, i regenerated the key alone it then worked like a charm !
i guess google parses allowed urls from the key string itself, not from updated settings

Additionnaly when I opened the requested URL in browser I found that the API call returned
{"domain": "usageLimits"}
I tried the above solutions without success.
Creating a new project from scratch solved the issue
Thanks @Danra, you helped, but I add this answer because your comment is default hidden.

I got frustrated and created a new project with a new key and it worked like a charm.
