I recently came across an error on SDDC Manager after few days from the deployment VCF 4.0.
‘Call failed to get Workload Management information. Got bad CSRF token – invalid csrf token’

I wasted some time in troubleshooting. Checked error log files etc…
The simple solution to this is to Logout from the browser, clear the cache and re-login. And that’s it.

Though this is a small blog, however this will definitely save your time. 😊
Happy learning.
