Login button is greyed out in vSphere Client after patching vCenter Server to 8.0 U3

How to Fix the vSphere UI Login Button Greyed Out After Upgrading to vCenter Server 8.0 U3

After patching your vCenter Server to version 8.0 Update 3, you may encounter a peculiar issue: the vSphere UI login button is greyed out, and the “Use RSA SecureID” option is automatically enabled, even though RSA SecureID is not configured in your environment. Here’s a step-by-step guide to troubleshoot and resolve this issue.

Symptoms

• • vSphere UI Login Button Greyed Out: After the patch, the login button in the vSphere UI may become unclickable.

• • RSA SecureID Enabled Automatically: The “Use RSA SecureID” checkbox is enabled by default, despite RSA SecureID not being configured.

• • Browser-Specific Issues: The problem may occur in some browsers but not others. For instance, Chrome may exhibit the issue, while Edge does not, or vice versa.

• • Incognito Mode Works: When using Chrome in Incognito mode, the issue might not appear.

Troubleshooting Steps

1. Clear Browser Cache and Cookies: Since the issue is browser-specific, start by clearing the cache and cookies of the affected browser. This can sometimes resolve UI-related issues caused by outdated or conflicting session data.
