### Description

When invoking jwt_verify with an expired JWT, it causes TLS termination with log print from the tls_server and tls_util.

While trying to debug the issue, I tried to give the method an invalid key path. I got the following log (as expected): ``` failed to read key file ```

Then the flow continued just fine (fallback to proxy_authorization).

When I gave it a correct file path, but the content is wrong, the problem still occurred. This makes me think the problem is in the method : ``` static int ki_jwt_verify_key(sip_msg_t* msg, str *key, str *alg, str *claims, str *jwtval) ```

### Troubleshooting

#### Reproduction

Use an expired JWT
