Power BI Apps Icon's are showing as broken.

[RossEdwards]

Power BI Apps are showing a broken icon suddenly:

Updating the icon in the 'Update App' section does not fix the problem.  It does not matter what file format is used.  This is occuring with all our icons and they all used to work.

after making a change to this:

Pressing 'Update App' reverts it back to being broken.

Hi @RossEdwards ,

I did a simple test but it didn't reproduce your problem.
Is it occurring in a specific browser situation? Does it help if you change browsers or refresh the network?

Best regards.

I'll assume its internal.  I've been told there are DNS changes having been made to our internal routing. I wonder if something has blocked the images.
