Occasional timeout while waiting on https://josm.openstreetmap.de/maps to be loaded

[JohnnyGPS]

What steps will reproduce the problem?

1. Start JOSM

What is the expected result?

JOSM start with no errors.

What happens instead?

• As soon as the welcome screen is loaded there is a popup dialog about a timeout while waiting for https://josm.openstreetmap.de/maps. Unfortunately I do not remember which java or javascript file that was generating the error.

• No imagery is available to be selected when that file have not been loaded.

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

• This do not happen every time (I would guess roughly about every second or third time).

• When this happens, restarting JOSM pretty much always yield the same result (timeout, no file loaded and no imagery available).

• Before version 11639 (in essence 11526 and earlier) I have never had this issue.

• The file is not all that large; only about 500 kB.

• A possible workaround that seem to work for me so far is to open a web browser and fetch the file. I do not know why that work, it was just a gut feeling thing ("What if I try this...?").
