+title: received unsupported Content-Type text/html; charset=utf-8
+---
+
+## What
+
+This happens when an exporter does not set the right response content type to `json` and instead just serves
+the page as HTML.
+
+This is most notable seen when using [intex/xpumanager](https://github.com/intel/xpumanager/blob/master/deployment/kubernetes/daemonset/base/daemonset-intel-xpum.yaml)
+
+You will see an error such as the below in Prometheus
+
+```text
+received unsupported Content-Type "text/html; charset=utf-8"
+```
+
+## Solution
+
+We need to set the `fallback_scrape_protocol` to `PrometheusText1.0.0`
+
+The documentation details it as
+
+```shell
+# Fallback protocol to use if a scrape returns blank, unparsable, or otherwise
+# invalid Content-Type.
+# Supported values (case sensitive): PrometheusProto, OpenMetricsText0.0.1,
+# OpenMetricsText1.0.0, PrometheusText0.0.4, PrometheusText1.0.0.
+[ fallback_scrape_protocol: <string> ]
+```
