SSLLabs stuck at Renegotiation Test

[namm2]

I found there are a lot (~ 6400 events/day) of error logs from SSLLabs that look like this:

  "_source": {
    "http_bytes": 0,
    "http_method": "GET",
    "http_path": "https://domain.tld:443/?SSL_Labs_Renegotiation_Test=User_Agent_May_Not_Show",
    "http_protocol": "https",
    "http_received_bytes": 138,
    "http_status": 400,
    "http_time_sec": -1,
    "http_uri": "/?SSL_Labs_Renegotiation_Test=User_Agent_May_Not_Show",
    "http_useragent": "SSL Labs (https://www.ssllabs.com/about/assessment.html)",
    "http_version": "1.0",
    "http_x_fwd_for": "x.x.x.x",
    "request_creation_time": "2022-03-04T08:59:03.877000Z",
    "request_processing_time": -1,
    "request_protocol": "HTTP/1.0",
    "response_processing_time": -1,
    "severity": "info",
    "source_type": "aws_s3",
    "ssl_cipher": "(NONE)",
    "ssl_protocol": "TLSv1.2",
    "target_processing_time": -1,
    "type": "load_balancer"
  }
}

It looks like SSLLab test is sticking at Renegotiation test of TLS v1.0(?). And also SSLLab-exporter container can't pull results either which is expected as the test wasn't finished:

{"level":"error","error":"context deadline exceeded","target":"domain.tld","timestamp":"2022-03-01T22:51:36.554160826Z","msg":"failed to fetch updates"}
{"level":"error","error":"context deadline exceeded","target":"domain.tld","timestamp":"2022-03-01T22:51:36.554213881Z","msg":"assessment failed"}

So the exporter is serving stale results.
