RuntimeException: Maximum zoom level too high

[diamantschiff@…]

What steps will reproduce the problem?

1. When I tried to download map data today from ​http://opengeofiction.net/api, it came up with this error. I am new to JOSM and not really sure how this happened.

What is the expected result?

It should have loaded in like normal.

What happens instead?

It opens an error box and won't load the data.

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

Can you please tell the configuration of the entry you use. Very likely you simply provided a zoomlevel to high, i. E greater than 24?

[Don-vip]

Please make sure you configured JOSM as documented on ​https://wiki.opengeofiction.net/wiki/index.php/OGF:Frequently_asked_questions#How_can_I_display_the_OpenGeofiction_map_as_background_in_JOSM.3F:

OSM default style tms[19]:https://tile.opengeofiction.net/osmcarto/{zoom}/{x}/{y}.png
TopoMap style tms[16]:https://tile.opengeofiction.net/topomap/{zoom}/{x}/{y}.png
Histor style tms[18]:https://tile.opengeofiction.net/tiles-histor/{zoom}/{x}/{y}.png

The number between brackets is the zoom level and cannot exceed 22 for the download window. It seems you entered an higher number.
