A few days ago, Openstreepmap obviously made some changes with their tile servers. They seem to block requests now, when the requests come from Electron applications. This is the case in most MagicMirror installations. As a consequence, MMM-RAIN-MAP does not show map tiles anymore.
I suspect, that also other modules are effected.
One possible fix is using another tile server for MMM-RAIN-MAP. One that still works at the moment, is the German fork “https://a.tile.openstreetmap.de/${z}/${x}/${y}.png”.
I will adjust the module soon, to use this tile server as a default.
You can also change the tile server by setting this property in the module config:

{
  mapUrl: "https://a.tile.openstreetmap.de/${z}/${x}/${y}.png"
}

Happy Warntag allerseits 😅

@rxlDavid I am working on OpenStreetMap support. A first draft version is already working. I’ll release it by the end of the week.

Dear fans and users of this module,

unfortunately Yahoo has switched off the Stock API in its previous form. The module is therefore currently unable to retrieve data (an error appears in the log).

The author of the library that Jast uses to retrieve data from Yahoo is working on a solution. At the moment, however, it is unclear whether there will/can be one.

I will monitor the progress of the development and keep you informed.

I am sorry that there is nothing else I can do at the moment but wait and see.

Update: The issue was fixed.

Please read the version’s release notes for instructions for updating this module.
