Vague Timeout Error Message

Customers have expressed concerns about some of our vague error messages in the past. While they are definitely getting better, there is another error message about timeouts that can be a little frustrating. 

In this case, our customer needed to completely log in and out of Salesforce to get rid of the issue, as well as refresh the page that this error popped up on. Adding a little clarity where possible would help save our customers time.

Thanks for all the hard work!
