Unable to reach Elastic Search from the Logs Data Plateform

Hello,

Yesterday I have done some Curl requests to the "https://gra1.logs.ovh.com:9200/ldp-logs/message" endpoint and everything went well.

Today, I launch the exact same request and it fails with the below response :
{
"error": {
"root_cause": [
{
"type": "auth_exception",
"reason": "Couldn't authenticate user logs-nb-xxxxx against any of the backends."
}
],
"type": "auth_exception",
"reason": "Couldn't authenticate user logs-nb-xxxx against any of the backends.",
"caused_by": {
"type": "multi_auth_exception",
"reason": null
}
},
"status": 403
}

The problem seems very similar to this one : https://community.ovhcloud.com/community/fr/elasticsearch-down?id=community_question&sys_id=bda171cc81528210f0780f07683eb2ea

The GrayLog plateform is still up and available, but the Elastic Search API button (https://gra1.logs.ovh.com:9200/_cluster/health?pretty=true) returns to me the same error response.

Is there something Down?

My Curl Request :
`curl -H 'Content-Type: application/json' -u 'logs-nb-xxxx:abcdef12345' -XPOST https://gra1.logs.ovh.com:9200/ldp-logs/message -d '{ "X-OVH-TOKEN" : "xxxxxx-xxxxx-xxxx-xxxx-xxxxxxx" , "test_field" : "Hello" , "short_message" : "Hello World", "host" : "OVHcloud_doc" }'`

Thanks
