Root Cause #2: The latest updates for vCenter and vSphere include new checks for common issues. The April 2019 and May 2019 release of 6.7 Update 2 include new health checks. Your vCenter will now warn you about things like problematic drivers and known memory leaks. These checks are only visible in the HTML5 client.
After upgrading the vCenter Server Appliance (VCSA) to version 6.7 Update 2, I tried to log in using the vSphere Client. After entering the credentials an endless blue running circle appears.
In the VAMI interface (https://vcsa-fqdn:5480) of the VCSA, the health statistics of all the components are green (okay) so I decided to reboot the VCSA.
After the VCSA reboot I encountered the same blue running circle when trying to log in using the vSphere Client. I tried Firefox and Google and the Internet Explorer browser. The only browser that worked was Internet Explorer. I never used Internet Explorer before so I tried to clear the cache of Google Chrome and Firefox using the following methods:
Clear cache, cookies and history of Google Chrome:
- Open Chrome.
- At the top right, click More
- Click More tools and then Clear browsing data
- Time range: All time
- Select Browser history, cookies and cache images and files
- Click Clear data
Clear cache and cookies of Firefox browser:
![Client Client](/uploads/1/2/5/8/125860152/198164552.jpg)
- Open firefox
- In the address bar enter: about:preferences
- Click Privacy & Security
- Under Cookies and Site Data select Clear Data
- Check Cookies and Site Data and Cached Web Content
- Click Clear and select Clear Now
After clearing the cache I was able to log in using the vSphere Client without the endless blue circle. So make sure to clear the cache of the browser(s) when experiencing the circle problem.
