Push request with api

Hi

I’m was trying to push log line with help of curl to my loki and got next response
HTTP/1.1 204 No Content

My payload looks like:
{“streams”:[{“stream”:{“label”:“letsencrypt”},“entries”:[{“timestamp”:“2022-04-30T11:09:45.000000+03:00”,“line”:“TEST!”}]}]

also I was trying to send timestamp in UTC format

{“streams”:[{“stream”:{“label”:“letsencrypt”},“entries”:[{“timestamp”:“2022-04-30T08:17:21.000000Z”,“line”:“TEST!”}]}]}

Error was the same.

Please help
