I have created HMI screens in WinCC and successfully configured the WinCC web server. I can access the web interface from the same computer using Internet Explorer without any issues. However, when attempting to access the web interface from a client PC, I am unable to view the screens, despite receiving a successful server status on the client PC. I have enabled remote communication in the Simatic shell and set port 80 as specified in the web configurator. Additionally, I have entered the server address in WinCC Viewer RT on the client computer. The error message I am encountering is attached below. If there are any steps I may be missing, your input would be greatly appreciated. Thank you in advance.
Could someone assist me in resolving my problem?
Based on what you're saying, it sounds like everything is set up correctly on the server side. Are you certain the issue isn't on the client side? I'd recommend checking your firewall settings on your client PC as it might be blocking inbound connections from your server. Also, try temporarily disabling any antivirus software on your client PC, they can sometimes block web handlers required for this kind of operation. It also might be an idea to check your LAN settings, as an incorrectly configured network might prohibit a successful connection to the server. Good luck and let us know how you get on!
From your description, it seems like you've done most things right. However, this kind of issue can sometimes be a result of incompatible software versions between the server and client or the use of a firewall. If there is a firewall active, it may be blocking incoming connections to port 80. You can try to temporarily disable the firewall and check if this solves the issue. Also, factor in that certain Windows updates may cause communication problems between WinCC and web client; ensure both are up-to-date. Compatibility of Internet Explorer versions is another aspect to consider since it's your access point to the web interface. Double-check these points and hopefully, you should be able to solve the issue.
From your description, it seems like you've done a pretty thorough job configuring your network, but it might be worth checking the firewall settings on both your server and client PCs. Occasionally, even if you've enabled the right port (in this case, 80), the firewall may block certain types of data exchange. Be sure to configure an exception for the client-server data exchange in your firewall settings. Furthermore, confirming that both the PCs are in the same subnet mask might solve network visibility issues. Lastly, consider checking the compatibility of the browser version on your client PC with the WinCC web server. It's possible that there are some browser-specific issues preventing successful interaction.
It sounds like you've done a lot of the groundwork already! One possible issue could be related to firewall settings on either the server or the client PC. Make sure that port 80 is open and not being blocked by any firewall software. Another thing to check is whether both machines are on the same network and that there are no network permissions preventing access. Lastly, try to access the web interface using another browser or clear your browser cache, as sometimes stale data can cause loading issues. Hope this helps!
It sounds like you're on the right track! Since you can access the web interface locally, it might be an issue with network settings or firewall configurations on the client PC or the server. Double-check that the client and server are on the same network and that there are no firewall rules blocking port 80. Also, ensure that the client’s browser is configured correctly and doesn't have any proxy settings that could interfere with the connection. It could also be worth trying a different browser or clearing the cache. Good luck!

Answer: Answer: The issue could be related to configuration settings on the client PC or network settings. Check if remote communication is properly enabled in the Simatic shell, the correct port (e.g., port 80) is set in the web configurator, and the server address is correctly entered in WinCC Viewer RT on the client computer.
Answer: Answer: Ensure that the client PC is properly configured to communicate with the WinCC server. Check network settings, firewall configurations, and ensure that the necessary ports are open for communication. Verify that the server address is correctly entered in the client software and that there are no connectivity issues between the client PC and the server.
Answer: Answer: Review the error message for specific details that may indicate the cause of the issue. Check the configuration settings on both the server and client side, including network settings, port configurations, and software settings. Ensure that all necessary steps for remote access are correctly configured and troubleshoot any potential connectivity issues.
