As I described in this StackOverflow question : Leaflet : Suddenly I'm getting this error message: Failed to load resource: the server responded with a status of 403 ()
I'm experiencing issues with loading and viewing openstreetmap tiles :
Failed to load resource: the server responded with a status of 403 ()
Based on the info here : https://operations.osmfoundation.org/policies/tiles/ the following are the requirements for the openstreetmap tiles usage:
Requirements
Heavy use (e.g. distributing an app that uses tiles from openstreetmap.org) is forbidden without prior permission from the [Operations Working Group](https://wiki.osmfoundation.org/wiki/Operations_Working_Group). See below for alternatives.
Clearly display [license](https://wiki.openstreetmap.org/wiki/License) attribution.
Do not actively or passively encourage copyright infringement.
Calls to /cgi-bin/export may only be triggered by direct end-user action. (For example: “click here to export”.) The export call is an expensive (CPU+RAM) function to run and will frequently reject when server is under high load.
Recommended: Do not hardcode any URL at tile.openstreetmap.org as doing so will limit your ability to react quickly if the service is disrupted or blocked.
Recommended: add a link to https://www.openstreetmap.org/fixthemap to allow your users to report and fix problems in our data.
Technical Usage Requirements
Valid [HTTP User-Agent](http://en.wikipedia.org/wiki/en:User_agent) identifying application. Faking another app’s User-Agent WILL get you blocked.
If known, a valid [HTTP Referer](http://en.wikipedia.org/wiki/en:HTTP_Referer).
DO NOT send no-cache headers. (“Cache-Control: no-cache”, “Pragma: no-cache” etc.)
Cache Tile downloads locally according to HTTP Expiry Header, alternatively a minimum of 7 days.
Maximum of 2 download threads. (Unmodified web browsers’ download thread limits are acceptable.)
Note: modern web browsers in standard configuration generally pass all the above technical requirements.
As far as I understand, I do respect all of them

What perplex me is that this happens only for the Basic Map Layer:
<LayersControl position="topleft">
<LayersControl.BaseLayer checked name="Basic Map">
<TileLayer
attribution='© <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
/>
</LayersControl.BaseLayer>
For example, it fails to load this tile:
https://b.tile.openstreetmap.org/13/4094/2723.png
Error message: Access Denied See: https://operations.osmfoundation.org/policies/tiles/
With the Topo Map Layer the visualization seems fine :
<LayersControl.BaseLayer name="Topo Map">
<TileLayer
attribution='Map data: © <a href="http://viewfinderpanoramas.org">SRTM</a> | Map style: © <a href="https://opentopomap.org">OpenTopoMap</a> (<a href="https://creativecommons.org/licenses/by-sa/3.0/">CC-BY-SA</a>)'
url="https://{s}.tile.opentopomap.org/{z}/{x}/{y}.png"
/>
</LayersControl.BaseLayer>
How to solve the issue? Looking forward to your kind help
