Map doesn't display
Yandex.Maps may not display due to the following reasons:
You are using a browser that we don't yet support. In this case a gray rectangle will display instead of the map.
Solution. Install a browser that works with maps:
Internet Explorer (version 11)
The list of browsers that work with our service is constantly expanding.
Security software (firewalls, antiviruses, ad blockers, etc.) has blocked the map. Unfortunately, certain settings within these programs may block map images. Usually the purpose of these settings is to trim banner ads, which are filtered by image size and URL.
Solution. Our map fragments are 256x256 pixels. Make sure that they are not blocked from loading and, if they are, unblock them. Settings are applied in different ways depending on what program you're using.
