★ VM cannot access from UIS Console

Standard UIS cluster

Customer feedback that after their routine maintenance, the UIS console function cannot be used, and an error message shows "failed to reach the host".

1.We checked the status of service casnovnc, which is in active and running state.

2.We checked the status of service tomcat8 and uis-core, they are all in active and running state.

3.We tried to restart the casnovnc, tomcat8 and uis-core service, but the issue is not resolved.

4.We want to know when console failed, what will output in the log.

We found that there is some sshhosttool error.

5. So the issue was related on SSHtool, we checked the database of mysql,

we found that the password was changed, and it is not synced to UIS web, so web page can not console.

Root cause was someone changed the password in backend, not in UIS web page.

Modify the password, and make sure the passwords are the same between UIS webpage and UIS backend.

After changing password, the issue was resoved.

NOTE: if you want to modify the root password, please modify the root password via UIS web page.
