Forti VPN連不上-- 'The server you want to connect to requests identification. Please choose a certificate and try again ( -5)'

 原本很舊的Forti防火牆升級後，有一些人的VPN就無法連線了，本來以為跟client端的vpn程式版本有關，因為公司內有4、5、6、7四種版本。

但後來發現這4個版本也都有不同的使用者可連上VPN，所以不是這個問題。

所以就用就錯誤訊息去查

後來是直接去IE的網際網路選項中，在進階設定裡把TLS1.1跟1.2打勾，就可以解決這個問題了。

Forti VPN cannot connect - 'The server you want to connect to requests identification. Please choose a certificate and try again (-5)'.

After upgrading an outdated Forti firewall, some people were unable to connect to the VPN. Initially, I thought it might be related to different versions of the VPN client software (versions 4, 5, 6, and 7) used within the company.

However, I later discovered that users with all four versions were able to connect to the VPN, so that wasn't the issue.

To troubleshoot, I investigated the error message further.

Eventually, I found that the solution was to go to the Internet Options in Internet Explorer and enable TLS 1.1 and 1.2 in the advanced settings. This resolved the problem.

卡巴斯基安全管理中心資料備份和還原程式 無法備份

 在升級卡巴斯基安全管理中心前，官方文件建議要用內建的資料備份和還原程式(Program Files (x86) Kaspersky Lab Kaspersky Security Center klbackup .exe)先做備份。

但在按下備份時，程式就會直接關閉，無法備份，沒任何訊息。

然後在事件檢視器裡，就找到一個相關的錯誤訊，原因是因為在執行備份時，會需要連上db，但目前登入的帳號是網域帳號，但當初安裝時是用本機帳號，所以會連不上db做備份，這時只要改用原本安裝的帳號來執行就可以備份了。

Before upgrading the Kaspersky Security Center, the official documentation recommends using the built-in data backup and restore program (Program Files (x86) Kaspersky Lab Kaspersky Security Center klbackup.exe) to perform a backup.

However, when pressing the backup button, the program immediately shuts down without any error message, making it impossible to create a backup.

Upon checking the Event Viewer, an error message related to the issue was found. The reason for this error is that during the backup process, a connection to the database (db) is required. However, the current logged-in account is a domain account, while the initial installation was performed using a local account. As a result, the backup process fails to establish a connection to the database. To resolve this issue, it is necessary to execute the backup using the original account used during installation.

Fortigate 免費的2個token刪除後無法加回..無法存取forti care

 Fortigate 本身就有含兩個token授權，可以指派其兩個帳號，做雙因子驗證使用。

在測試時，設備本身有簽維護，但版本很舊，在設定時發生一些狀況，後來就把它給刪了，想說應該可以重新加回來，上網找了一下，可以用全都是0的預設設號匯入就行了。

結果~不行，然後有一個按鈕是寫重新下載授權，按下去就跳出無法存取forti care，一整個搞不定。

明明就有維護，還不給我存取，最後就依廠商建議，系統太舊原廠不支援，升級到最新試試，就可以了。

After deleting the two free tokens on FortiGate, I couldn't add them back, and I couldn't access FortiCare.

FortiGate itself comes with two token licenses, allowing for the assignment of two accounts for two-factor authentication purposes.

During testing, the device had an existing maintenance agreement, but it was running on a very outdated version. While configuring it, some issues occurred, so I decided to delete it, thinking that I could add it back later. I searched online and found that I could import a default configuration with all zeros.

However, it didn't work. There was a button labeled "Re-download License," but when I clicked it, it showed an error message saying it couldn't access FortiCare. It was quite frustrating.

Despite having an active maintenance agreement, I was denied access. Finally, following the vendor's suggestion, I upgraded the system to the latest version, and that resolved the issue.
