當發現自己無法連接到網站，電郵軟件無法連接伺服器，或無法訪問cPanel和webmail登入畫面，顯示錯誤信息：服務器連接超時Server connection timed out。很可能是您已觸發防火牆規則，IP地址被伺服器的防火牆封鎖。
您可以嘗試訪問cPanel和webmail。
網頁寄存cPanel登入網址：https://cpanel.yourdomain.com
例子 : 以 example.com 作示範: https://cpanel.example.com
Webmail電子郵件登入網址：https://webmail.yourdomain.com
例子 : 以 example.com 作示範: https://webmail.example.com
因此，如果您發現自己無法連接到網站，電郵軟件無法連接伺服器，或無法訪問cPanel和webmail登入畫面，很可能是您已觸發防火牆規則，IP地址被伺服器的防火牆封鎖。請立即登入客戶服務中心，聯繫求助桌Helpdesk，我們很樂意為您解鎖IP地址。您可以到 https://whatismyip.hk/ 查看IP地址。
請參考求助桌Helpdesk提供的資料，避免IP地址再次被伺服器的防火牆封鎖。
主要原因如下及解決方案：
1. 短時間內過多次cPanel登錄失敗
如果您已嘗試幾次輸入登錄資料後仍然無法登錄cPanel，請不要繼續嘗試。一旦超過了伺服器可接受的上限，IP地址即被伺服器的防火牆封鎖。
如果忘記 cPanel 密碼，請登錄客戶服務中心 https://hostingspeed.net/account/hmanage.php 帳戶中 > 按下 "按此重設寄存戶口 / cPanel / FTP 登入密碼 Reset cPanel Password"
2. POP3 / IMAP / SMTP 或 Webmail 登錄失敗
A) POP3 / IMAP 登錄連線失敗 (例如接收信件時出現 0x800ccc0D, 0x800ccc0E 0x800ccc0F 等錯誤訊息)
如果您在電郵軟件內收到與 POP3 / IMAP 身份驗證失敗的相關的錯誤，這代表電郵軟件內帳戶的登錄憑據可能不正確。在這種情況下，電郵軟件將繼續不斷嘗試訪問伺服器，這也可能導致IP地址被伺服器的防火牆封鎖。您可以參考以下連結的電郵軟件設置:
郵件收發設定 Email Setting - Outlook office 365
B) SMTP 登錄連線失敗
當SMTP身份驗證資料無效或不正確時會導致IP地址被伺服器的防火牆封鎖，因此您無法從電郵軟件發送郵件。請確保SMTP登錄的身份驗證正確。您可以參考以下連結的SMTP 登錄設置:
開啟Microsoft Outlook 的SMTP 驗證 Enable SMTP Authentication in Microsoft Outlook
C) Webmail 登錄失敗
如果您已嘗試幾次輸入登錄資料後仍然無法登錄Webmail ，請不要繼續嘗試。一旦超過了伺服器的上限設定，IP地址即被伺服器的防火牆封鎖。為避免這種情況，請登入cPanel 透過 "Email Account" 重設電郵密碼。
如果您仍然無法使用舊密碼登錄或設置在電郵軟件內，請登入求助桌Helpdesk解鎖IP地址後登錄cPanel重置電郵密碼。
3. 電郵軟件設定不正確
電郵軟件設定不正確也可能導致IP地址被伺服器的防火牆封鎖，因此請檢查電郵軟件設定是否正確，如問題持續，您可以考慮自行把電郵備份，然後從電郵軟件刪除相關的電子郵件帳戶，從頭開始設置。您可以在此參考正確的電郵軟件設置 : https://help.hostingspeed.net/hc/zh-tw/sections/115000299551-%E9%9B%BB%E5%AD%90%E9%83%B5%E4%BB%B6%E8%A8%AD%E7%BD%AE
4. FTP 登錄失敗
請確保您的 FileZilla 軟件使用正確的登錄資料及設定。
你可以在這裡參考正確的 FileZilla 軟件設置:
(FTP) 如何使用 FileZilla 來上傳檔案 How to upload my web file via FileZilla?
5. 網頁登錄失敗
當網站上有身份驗證表格或受保護的目錄時，這可能會導致IP地址被伺服器的防火牆封鎖。請確保您使用正確的登錄資料。
When you find yourself unable to connect to the website, email software cannot connect to the server, or cannot access the cPanel and webmail login page, the error message: Server connection timed out. Most likely, you have triggered the firewall rule and your IP address is blocked by the server's firewall.
You might try to access cPanel and webmail.
cPanel login link : https://cpanel.yourdomain.com
Take example.com as an example : https://cpanel.example.com
Webmail login link : https://webmail.yourdomain.com
Take example.com as an example : https://webmail.example.com
Therefore, if you find yourself unable to connect to the website, unable to connect to the server with your email software, or unable to access the cPanel and webmail login page, most likely you have triggered the firewall rule and your IP address is blocked by the server's firewall. Please contact the Helpdesk and we are happy to help you unblock your IP address. You can check your IP address at https://whatismyip.hk/
Please refer to the information provided by Helpdesk to avoid IP blocked again.
The main reasons and solutions are as follows:
1. Multiple cPanel login failures within a short period of time
If you have tried several times to enter your login information and still cannot log in to cPanel, please do not continue to login. Once the server's acceptable limit is exceeded, the IP address will be blocked by the server's firewall.
If you forget your cPanel password, please log in to the Customer Service Center at https://hostingspeed.net/account/hmanage.php > Click "Click here to reset your hosting account / cPanel / FTP login password Reset cPanel Password"
2. POP3 / IMAP / SMTP or Webmail login failure
A) POP3 / IMAP logging connection failure (e.g. 0x800ccc0D, 0x800ccc0E 0x800ccc0F error message when receiving mail)
If you receive an error related to POP3 / IMAP authentication failure within the email software, this means that the login credentials for the account maybe incorrect. In this case, the email software will continue to try to access the server, which may also cause the IP address to be blocked by the server's firewall. You can refer to the following link for email software settings:
郵件收發設定 Email Setting - Outlook office 365
B) SMTP logging connection failure
When the SMTP authentication data is invalid or incorrect, the IP address is blocked by the server's firewall, so you cannot send emails from the email software. Please make sure the authentication of SMTP login is correct. You can refer to the following link for SMTP login settings:
開啟Microsoft Outlook 的SMTP 驗證 Enable SMTP Authentication in Microsoft Outlook
C) Webmail login failure
If you have tried several times to enter your login information and still cannot log in to Webmail, please do not continue to login. Once the server's limit is exceeded, the IP address will be blocked by the server's firewall. To avoid this, please login to cPanel and reset your email password through "Email Account".
If you are still unable to log in with your old password or set it in your email software, please log in to Helpdesk ask for IP unblock and log in to cPanel to reset your email password.
3. Incorrect email software settings
Incorrect email software settings may also cause the IP address to be blocked by the server's firewall, so please check if the email software settings are correct. If the problem persists, you may consider to back up your email data and delete the relevant email account from the email software. Then, setup the account again. You can refer to the correct email software settings here
4. FTP logging failure
Please ensure that your FileZilla software uses the correct login information and settings.
You can refer to the correct FileZilla software settings here:
(FTP) 如何使用 FileZilla 來上傳檔案 How to upload my web file via FileZilla?
5. Web logging failure
When there are authentication forms or protected directories on the site, this may cause the IP address to be blocked by the server's firewall. Please make sure you are using the correct login information.
