Hi @Jiu_Kam, I am so sorry for the trouble. When first reading this I thought it might be related to this post which appears to be related to the logic introduced with user management.
However, it seems this is not quite the same. I could, however, not reproduce the behaviour based on your description alone. Are you perhaps using a reverse proxy server not proxying communication between your n8n server and the browser here?
Are you also having this problem when running n8n locally?
