I don't think there is anything we can do. If the server is not available, the plugin cannot work, so the alert window is okayish.

Replying to gaben:

Server responded with HTTP 429

I don't think there is anything we can do. If the server is not available, the plugin cannot work, so the alert window is okayish.

But still I think there're any problem in the JOSM or plugin itself, not the Wikipedia server limiting. Every try without any time fails with server error, but if I restart JOSM, the first execution succeeds again.

Also I've updated the JOSM before I suffered this error. The old version never showed this bug ever, regardless of the number of tries.

I never checked, but they can throttle based on user agent. If the new is throttled, you could get this behaviour.
