Java Profiler Unavailable After the Root Certificate Is Installed

After the root certificate is installed as prompted, the Java Profiler still cannot be used.

The certificate is not installed correctly. Go to the local path displayed in the download information to reinstall the certificate. Ensure that the certificate is stored in the Certificate Store directory under Trusted Root Certification Authorities.
Not all IDE instances are closed. Close all IDE windows and processes and try again.
The IP address protected by the certificate is inconsistent with the actual IP address through which you access the tool. The former one is the Hostname_IP that you specify during tool installation. You can run the hostname -I command on the server to view the IP address. The tool address that you access via the Internet rather than on the LAN is not protected by the certificate. Do as follows so that your access to the HyperTuner domain name can be protected by the certificate.

(Optional) Grant the user the permission to modify the hosts file.
Run Windows PowerShell as the administrator.
```
cacls %WINDIR%\System32\drivers\etc\hosts //e /g users:c
```
Edit the hosts file.
Add or modify the following item in the file. The IP address must be the one that you use to access the tool, and the host name must be HyperTuner.
```
XXX.XXX.XXX.XXX HyperTuner
```
Restart the IDE.
Reconfigure the option of checking the domain name of the remote server. This option is enabled by default after a certificate is installed. After it is enabled, related information is displayed in the IP Address area.
