[TiDB Usage Environment] Production Environment / Test / Poc
[TiDB Version] v7.5.1
[Reproduction Path]
Normal deployment using tiup
[Encountered Issue: Issue Phenomenon and Impact]
The following error appears when logging into the dashboard:

Checking the tidb-deploy/tidb-dashboard-8080/log/tidb_dashboard.log log reveals the following error:

ps shows that ng_monitoring started normally, no issues

Executing the following command to check the monitoring_servers configuration is normal

tiup cluster edit-config <cluster>


Checking the tidb-deploy/prometheus-8249/conf/ngmonitoring.toml configuration is also normal

How should I troubleshoot this?

My tiup is v1.14.0, do I still need to upgrade?
