WIF10201: No valid key mapping found for securityToken

[FranckLamon]

Hello,

For some days I try to solve a problem accessing the autorization Server. but every time I get the following error after you enter my username and password:

WIF10201: No valid key mapping found for SecurityToken 'System.IdentityModel.Tokens.X509SecurityToken' and issuer 'http://identityserver.v2.thinktecture.com/company'.

I validated that the thumbprint is good and I create this environment from a copy of another that is functional.

Thx for your help
