+# 30. Fix refresh token with OIDC using `QueuedInterceptor`
+
+Date: 2023-09-11
+
+## Status
+
+- Issue: 
+
+[1974](https://github.com/linagora/tmail-flutter/issues/1974)
+
+## Context
+
+- Requests still return `401` after retrieving a new token. The application automatically logs out
+
+## Root cause
+
+- When executing tasks concurrently, they are pushed into the `Queue` along with the old `header` values (the old authentication is retained). 
+So when the first request receives a `401` error and tries to get a new token, it will be updated with the new authentication header value.
+
+## Decision
+
+- Use `QueuedInterceptor` to serialize `requests/responses/errors` before they enter the interceptor. 
+If there are multiple concurrent requests, the request is added to a queue before entering the interceptor. 
+Only one request at a time enters the interceptor, and after that request is processed by the interceptor, the next request will enter the interceptor.
+- Try to make a `retry` request up to 3 times when receiving a `401` error. Aims to update the new token value on `memmory` to requests in the `queue`.
+
+## Consequences
+
+- The following `requests` were completed successfully. The application is not automatically logged out
