Description

We have 2 primary server load balanced and 1 secondary server. We have hosted Identity server on all 3 servers. It is working perfectly fine with 2 primary servers. However, on the secondary server when i access the identity server, I get the following error:

Error:
The key {63543669-de79-40e2-bb19-072ff2a9bd92} was not found in the key ring. For more information go to https://aka.ms/aspnet/dataprotectionwarning

Error unprotecting the IdentityServer signing key with kid A50B677F0BDFC7BDA3375583FD527D2B. This is likely due to the ASP.NET Core data protection key that was used to protect it is not available. This could occur because data protection has not been configured properly for your load balanced environment, or the IdentityServer signing key store was populated with keys from a different environment with different ASP.NET Core data protection keys. Once you have corrected the problem and if you keep getting this error then it is safe to delete the specific IdentityServer signing key with that kid.

Can you please let me know what's the issue here?

Looking forward to hear from you soon.

Thanks!

Can you check if ASP.NET Core Data Protection is configured properly in your application?
