Why Can't I Access the Flink Web Page?

Issue

The Flink web page cannot be accessed through http://JobManager IP:Port of the JobManager.

Answer

The IP address of the computer you used has not been added to the whitelist of the Flink web page. To solve the problem, perform the following operation:

  1. Check the configuration file conf/flink-conf.yaml on the client.
  2. Check whether the value of the jobmanager.web.ssl.enabled parameter is false.
    • If the value is not false, change the value to false.
    • If the value is false, perform the next step.
  3. Check whether the IP address of the computer you used has been added to the jobmanager.web.access-control-allow-origin and jobmanager.web.allow-access-address parameters. If the IP address has not been added, add it to these two parameters. Example: 
    jobmanager.web.access-control-allow-origin: 192.168.252.35,192.168.24.216
jobmanager.web.allow-access-address: 192.168.252.35,192.168.24.216
