Data proxy error | grafana

Hi Everyone,

We are using Grafana 7.1.3 where multiple dashboards are configured to view the KPI data coming via prometheus.

However sometime we are getting below error while loading the dashboard.

t=2021-07-20T14:34:43+0530 lvl=eror msg=“Data proxy error” logger=data-proxy-log userId=1 orgId=1 uname=admin path=/api/datasources/proxy/1/api/v1/query_range
error=“http: proxy error: context canceled”.

Please suggest how we can resolve it.
