You removed the server names?!
Response from developer
We are deeply sorry for this situation. This is a known issue that occurs when you use the "Migrate to Easy Mode" feature, or "Update Hosts" in Easy Mode. Our upcoming version v3.4 will address this issue. This version will also provide naming capabilities. For now, please switch back to "General Mode" as a temporary solution. If you have any other question, please feel free to email it to support@geovision.com.tw with details, we will provide further assistance.
