Authentication failed for User VCFUI during VCF upgrade

During a recent VCF upgrade from version 4.5 to 4.5.1, I was faced with the following error:

'Session middleware wrapper failed to initial and all retry attempts. Cannot continue. Throwing error from session middleware - password authentication failed for user "vcfui"'

I found the instructions in https://kb.vmware.com/s/article/77551 resolved the issue and I was able to continue with my VCF upgrade!

As always, thanks for reading!
