There could still be an issue--Server and Desktop render maps based on the machines they are installed on, so when you view the online examples, you are connecting to someone else's machine to render the map.
At least, that is my understanding. I'd suggest contacting email@example.com if maps are not rendering in Desktop.
Hi Matthew & Allan
1. Are the online maps working in Desktop (without publishing)?
2. Are the online maps working if the workbook is published to Tableau Public?
3. Are the online maps working if the workbook is published to your Tableau Server?
If yes to 1 & 2, then you are connecting to mapfluence - which is run by Urban Mapping (Tableau's 3rd party mapping provider).
If no to 3, it's likely your server admin hasn't allowed mapfluence (the online mapping) through the ports.
First of all, nice name.
I'm currently only using Desktop, so the answer to question 1 is no. I have not yet tried anything on Public or Server. I'm guessing I will need to work with my IS department on this issue, but I would like some ammunition before I go to them. Is there a way to test my connection to mapfluence. I thought using the "Miami/Havana" links from within IE would accomplish this, but Matthew's comments have me thinking otherwise.
I did read the link you provided. My computer is pretty locked down for the time being, so I didn't try any proxy changes.
I added the WMS server you mentioned and received the following error message:
Internet communication error: Failure when receiving data from the peer
Does that point towards a security policy issue? I'm heading home for the day, but will check back tomorrow.
Yep. It looks like Port 80 on your computer is locked down.
