When you remove and add the service account in View administrator > View configuration > Servers > vCenter Servers for vCenter and Composer, you should use the User Principal Name format of the account, for example:
Do not use the down-level logon name like DOMAINNAME\username.
I know this sounds ridiculous, but this tip was a recommendation from VMware support for a different issue, and helped me.
This is due to a rare bug in View 7.x.
Perhaps it can help you in this issue.
Sincerely,
