Hi everyone 
Thanks for reporting this issue, I’ve investigated.
This is indeed a problem affecting all users; it’s nothing specific to your accounts.
For a reason I don’t know, one of the API calls I use has not been working since March 5.
I’ve contacted Enedis to find out whether there has been an API change (normally not according to their documentation), or if it’s just a bug on their side.
I’ll keep you updated on their response
