How do I perform a certificate exchange?

You can perform the certificate exchange as follows:

• Deposit the new certificate on the application server in the IIS Manager and set it up in the bindings on port 443.
• Afterwards stop the service "IZYTRON.IQ BackEnd SyncService
• Now store the Thumbprint in the files
  • C:\Program Files\Gossen-Metrawatt\IZYTRON.IQ BackEnd SyncService\IZYTRON.IQ.SyncSvc.exe.config
  • C:\inetpub\wwroot\IZYTRON.IQ\web.config
• put the thumbprint of the new certificate in capital letters
  • serviceCertificate findValue="[certificate thumbprint]" storeLocation="LocalMachine" storeName="My" x509FindType="FindByThumbprint"
• then restart the service

Now the synchronization can be accessed and performed on a secured connection again.

If the following error message appears in the Eventviewer under windowsLogs/Application when starting the service IZYTRON.IQ BackEnd SyncService:

This error message is usually caused by copying the certificate properties from this window.
The reason for the error message is that an invalid special character was copied along.

Please check the configuration files for the presence of invisible special characters in the certificate entry. You can find these special characters by using the arrow keys. Invisible special characters in the text can be recognized if the cursor jumps only after clicking twice.

• Remove this character and save the configs
• Restart the service

A bug has been observed in several releases of Windows Servers, but has not been fixed until 2019.
