Api(dot)securerpc(dot)com/v1 --> Response: flashbot-Method is not supported

Describe the bug flashbots methods are not working api(dot)securerpc(dot)com/v1. I always get a Response: “Method ‘METHODNAME’ is not supported.” tested with flashbots_getUserStats and eth_callBundle

To Reproduce sent header: {‘X-Manifold-Signature’: ‘0x9889FAD4DB79deC094264De686b35CB557C7BD37:0xf463a4253957c9859af89bd1db99bab1e6c11e774ad18bb04b4bbfd015d2bd950850ccd493e3c5c59560177605d9c1f2bb9953ab98bf96990c8754c6204eb3171c’, ‘Content-Type’: ‘application/json’} sent body: ‘{“jsonrpc”: “2.0”, “id”: “gUS_5BvR2ulyQ”, “method”: “flashbots_getUserStats”, “params”: [{“blockNumber”: “0xec2810”}]}’

response: {‘error’: {‘code’: -32601, ‘message’: “Method ‘flashbots_getUserStats’ is not supported.”}, ‘id’: ‘gUS_5BvR2ulyQ’, ‘jsonrpc’: ‘2.0’}

Additional context 2 weeks ago flashbots_getUserStats worked this way. Has there anything changed?
