Not to able to open URL with host name but working fine with IP

Use NSLOOKUP (Windows) or DIG (Linux) to verify that DNS is correct. Also if you set up the VIP for port 443 then ensure that you are using "HTTPS" with your URL. Also add a redirect for port 80 traffic to HTTPS.

Hello,

Launch the powershell from you client or the cmd.exe and try to ping the name.

Verify that it is resolving the good IP address.

Maybe you have an entry in your host file that do not correspond to the real IP address.

Yes done these as well..

DNS team saying DNS entry done correctly.

Pls. suggest further.

Try using TELNET to see if you can get a TCP session going. For example if your VIP resolves in DNS as then use "telnet 80" if the VIP is on port 80. If telnet connects then you know the VIP is active. Also make sure that the server can't communicate directly with your workstation without going through the F5. If it can then enable SNAT AUTOMAP in your VIP configuration.

How to check this :

Also make sure that the server can't communicate directly with your workstation without going through the F5. via Telnet to the server on particular port.

Please add a comment and show: * output of DIG or NSLOOKUP * VIP definition * URL being used to access site * Output from traceroute from workstation to server and from server to workstation
