Automated cbcollect host error pop-up long and inconsistent

Applies to 3.0 build 918

Invalid hostname should just give the same nice red error alongside the input box rather than a pop-up.

Go to Log->Collect Information
Select "upload to couchbase"
Enter an invalid hostname

A box pops up stating:

"Failed to check reachability of https://www.klfjhasdlkfjhasldkfjhasdlkfjahsdf.com/david/hello/: {failed_connect,
[{to_address,
{"www.klfjhasdlkfjhasldkfjhasdlkfjahsdf.com",
443}},

]}

An inline red error message of "failed to connect to host" would be much cleaner.
