When you say "sometimes" this sounds to me like you are using the AddTemporarySigningCredentials option in IdentityServer4.

This means that new key material will get created on each startup of the host.

In your case the MVC application has a cached version of the key material and thus gets out of sync.

Try setting static keys - e.g. using an X509 cert:
