Hi, you may try to refresh the page after several seconds. If it's still wrong, are there any errors shown in frontend developer tools (F12 in Windows) in Chrome?

There are no errors shown in frontend developer tools (F12 in Windows) in Chrome. So I'm confused.

from sentinel.

Are there any exceptions or error log in you ${home}/logs/csp/record.log? Please check your VM arguments passed to sentinel-dashboard. It should be like this:

java -Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -jar target/sentinel-dashboard.jar

The content of record.log as follows:(not for this time,I restart the application using your advice and it works)

So, java -Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -jar target/sentinel-dashboard.jar can work.
However, go into directory "target" and use java -Dserver.port = 8080 -Dcsp.sentinel.dashboard.server = localhost：8080 -jar sentinel-dashboard.jar can not work.

I found the problem is that the command I copy and edit from the website "https://github.com/alibaba/Sentinel/wiki/%E6%8E%A7%E5%88%B6%E5%8F%B0" is wrong which contains Chinese charactor.
So,both java -Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -jar sentinel-dashboard.jar and java -Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -jar target/sentinel-dashboard.jar can work.
