Any additional Information

Hi - can you use a browser and check the URL for the Avatar please?

Think I have seen something similar but would like to check.

Check with

http://[ServerIP]: 3000/avatar/[UserName] or http://[ServerIP]:3000/avatar/[UserName]?etag=[Code ~~]

There is no difference from the URL where the avatar image was output normally.
