Hi, How are you? I am Alan. I will be happy to assist you today. I appreciate your contact!
If you cannot access the server on a specific PC but it works fine on other computers, it could be caused by several reasons.
Check your firewall settings, Windows firewall may be blocking the connection. Go to Settings > Update & Security > Windows Security > Firewall and network protection.
Temporarily disable the firewall and see if you can access the server. If it works, set up a rule to allow the connection.
Verify that the server is configured to accept connections from the problematic PC. This may include checking specific whitelists or blocks on the server.
Test Ping and Traceroute, open Command Prompt and use ping [server address] to see if there is a response from the server.
Use tracert [server address] to check the path to the server and identify where the failure may be occurring.
I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
Best,
Alan
