Hi Regis,

1. Prepare an updated TLS certificate.
2. Copy the new TLS certificate to ifsroot\config\certs.
3. Open ifsroot\config\ifscloud-values.yaml.
4. Update and verify "certificateFile" and "certificatePassword" as appropriate.
5. Rerun mtinstaller action.

installer.cmd --set action=mtinstaller

Then verify the certificate validity dates. An example with openssl:

openssl s_client -connect <url>:443 | openssl x509 -noout -dates

Best regards -- Ben
