Please clarify the following:

• Can you tell me the name of the website you're having issues accessing? (Don't post the link, just tell me the name or post a screenshot.)
• See if the same behavior occurs in an InPrivate/Incognito window. To open the InPrivate/Incognito window, open the browser and press "Ctrl + Shift + N". (For Microsoft Edge and Google Chrome)
• Can you test to see if the site loads on another device? It could even be a smartphone.
• Do you have any VPN software installed? (Even if it's not running at the moment) If yes, which one?

Looking forward to your reply.

On slow or congested Internet connections, Windows can time out before a website responds, causing connection timeout errors.

On Windows, one supported way to reduce these timeouts is to increase how long TCP waits before giving up on a data segment. This is done by adding or adjusting the TcpMaxDataRetransmissions registry value.

Important: Editing the registry incorrectly can cause serious system problems. Back up the registry first and only proceed if comfortable with these steps.

1. Open Registry Editor
   1. Press Windows key, type regedit, and press Enter.
   2. If prompted by UAC, select Yes.
2. Navigate to the TCP/IP parameters key
   1. In Registry Editor, go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. Create or modify TcpMaxDataRetransmissions
   1. On the Edit menu, select Add Value (or right‑click in the right pane and select New > DWORD (32-bit) Value).
   2. Name it: TcpMaxDataRetransmissions.
   3. Set Value type to REG_DWORD.
   4. Set the Value data to 10 (Decimal). The default is 5; increasing to 10 allows more retransmission attempts.
4. Restart the computer
   1. Close Registry Editor.
   2. Restart Windows so the change takes effect.

If connection timeouts still occur after testing for a while, increase the value again (for example, to 20 Decimal) using the same steps.

Note: This change may only reduce the number of timeout errors. If the website is down, unreachable, or there are issues with the router/ISP, those underlying problems must be fixed separately.
