15609	Accessing tiles from the download dialog behind a proxy	bxl-forever	team	"==== What steps will reproduce the problem?
1. Use a proxy
2. File > Download data
3. Scroll the area a bit so that JOSM will download new tiles

==== What is the expected result?
The tiles should be downloaded normally when the map scrolls.

==== What happens instead?
Several warning dialogs (apparently equal to the number of new tiles that are loaded).
But the tiles are loaded properly and JOSM works normally after that.
It is just considerably annoying because the download window is almost unusable.
I did not encounter this problem with former versions, it appeared with the upgrade to version 13170.
When I use the same machine with a connection where I don’t have to use a proxy, version 13170 works fine.

==== Please provide any additional information below. Attach a screenshot if possible.
