Token validation issue - wso2

Question

Why does this error occur when I do request? How to fix it? WSO2 4.1.0
I don't understand where to look for the problem, this URL is nowhere to be found.
Who can suggest something?

Answer 1

You can specify your JWKS configurations in the deployment.toml as shown below.
[[apim.jwt.issuer]]
name = "https://localhost:9443/oauth2/token"
jwks.url = "https://localhost:9443/oauth2/jwks"
[[apim.jwt.issuer]]
name = "wso2is"
jwks.url = "https://localhost:9445/oauth2/jwks"

Answer 2

Sometimes an empty hostname in deployment.toml could be the cause of this error
[server]
hostname = ""
node_ip = "$env{NODE_IP}"
base_path = "https://$ref{server.hostname}:${carbon.management.port}"
[transport.https.properties]
proxyPort = 443
To prove that its your problem you can go to https://<host>:<port>/carbon console and then check your values inside
Idenity -> Identity Providers -> Resident -> Inbound Authentication Configuration -> OAuth2/OpenID Connect Configuration
There you should see your https:9443/oauth2/jwks becouse of your initial hostname value.
