I am using Teleriks RadMap silverlight control (in a https site) with OpenStreetMap as the provider, I am unable to view any map data so investigated using fiddler.

I initially got:

The remote server (a.tile.openstreetmap.org) presented a certificate that did not validate, due to RemoteCertificateNameMismatch.

SUBJECT: CN=*.openstreetmap.org, OU=Domain Control Validated - RapidSSL(R), OU=See www.rapidssl.com/resources/cps (c)10, OU=GT33044578, O=*.openstreetmap.org, C=GB, SERIALNUMBER=Dgi7Lfgx7wbOkaryb/3olT0IlEQOS5b9
ISSUER: OU=Equifax Secure Certificate Authority, O=Equifax, C=US
EXPIRES: 14/02/2012 23:38:04

(This warning can be disabled by clicking Tools | Fiddler Options.)

HTTPS connection failed.

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it
   at Fiddler.ServerChatter.CreateConnectedSocket(IPAddress[] arrDestIPs, Int32 iPort, Session _oSession)
   at Fiddler.Session._handleHTTPSConnect()

In my browser I added a.tile.openstreetmap.org as an allowed exception and that connection now seems to be accepted, however I am still seeing no map data and for requests to b.tile.openstreetmap.org and c.tile.openstreetmap.org I see:

HTTPS connection failed.

System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
   at Fiddler.ServerChatter.CreateConnectedSocket(IPAddress[] arrDestIPs, Int32 iPort, Session _oSession)
   at Fiddler.Session._handleHTTPSConnect()

I am not sure what to do to solve this so any advice appreciated.

https is available from today (5th Jan 2014) on a,b,c.tile.openstreetmap.org. Initially only as a test.

We don't support https access to our tiles - it's just too expensive from a CPU point of view given the number of tiles that we serve.

Ok, thanks, I will see if I can get the control to request http only.

I understand the need to keep cpu load down.

Unfortunately, with https for the tiles, it's very difficult to embed a map in an https web page because most browsers will present the user with a scary warning about "unsecured" parts of the web page.

I wonder if it would be possible to offer both http and https - for people who are showing an http, they can use the http version (and reduce load). But for those displaying the map in an https page, we could choose the https page?

OSM is not a general-purpose, unlimited-access tileserver. If you want to embed tiles in your webpage but need more than the basic, limited-bandwidth service provided by OSM, you are encouraged to download planet.osm and render your own.
