Viewpoint: Not able to access VP Portal via Google Chrome

Hi ,
One of my user getting an error "Server has a weak ephemeral Diffie-Hellman public key" when he is trying to access viewpoint Portal via Google Chrome, even after he tried the following options
1) Cleared the cache and rechecked
2) Alternate way to fix the issue
Step 1 : Place the “Google Chrome” icon on the desktop.
Step 2: Right Click on the “Google Chrome” icon and select the option “Properties”.
Step 3 : Enter the below highlighted text in the field “Target” (which is editable).
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --cipher-suite-blacklist=0x0088,0x0087,0x0039,0x0038,0x0044,0x0045,0x0066,0x0032,0x0033,0x0016,0x0013"
Step 4: Click on “Apply” button and Click on “OK”.
Step 5: Open the “Google Chrome” as usual.
 
But still getting any error.
Is there any other solution to fix this issue.
 
Thanks,
Harsha.
