Caching Issue

[ghost]

Hello,

I think there is a problem with caching but I can't seem to trace it.

I have a CartoDB setup from this docker on a server so I can access it remotely and share with some colleagues. When I publish a map and share the link, after a few hours I get these errors:

http://clmc.site44.com/error.png

The errors are inconsistent though which makes me think it is something to do with caching. For example:

1. I open the link to the map on "computer 1" a few hours after publishing and the errors appear
2. I open the link to the map on "computer 2", the map loads fine, no errors
3. I go back to 'computer 1' and reload the map from the link, no errors

You are more than welcome to visit the map:

http://95.216.136.247/user/dev/builder/0025cd8c-3a2f-4955-ada8-c71cc8e4258a/embed

The map is passworded: map

The same happens on maps I have published without passwords, privately and publicly.

Any help would be greatly appreciated!
