<h3 dir="auto">How to reproduce the issue?</h3>
<ul dir="auto">
<li>When opening <a href="https://www.openstreetmap.org" rel="nofollow">https://www.openstreetmap.org</a> using the standard layer, the tiles are not shown (all grey)</li>
<li>This only occurs in Firefox (currently 117.0 (64-Bit)) since a couple of days, works fine in e.g. Edge on same PC/network</li>
<li>Occurs also in Firefox safe mode without any extensions active</li>
<li>Looking into the console it shows HTTP 418 responses from tile.openstreetmap.org</li>
<li>Opening a tile URL directly shows the tile (e.g. <a href="https://tile.openstreetmap.org/14/8616/5706.png" rel="nofollow">https://tile.openstreetmap.org/14/8616/5706.png</a>) correctly</li>
</ul>
<p dir="auto">I am sorry if this is not the correct place to raise this issue, but I could not find another suitable place during my search.</p>
<p dir="auto">Thanks and best regards!<br>
