Where is the Composer Conversation History Stored After Hostname Change?

Hello!

Could someone please advise where the Composer conversation history is stored? I’m working on a remote server and today I changed the hostname. As a result, the history from all folders has disappeared.

I assumed that the history was tied to the specific folder I was working in, but now all chats have vanished. Could anyone explain where the history is located and how to control the process of transferring chats from one folder to another?

Thank you in advance for your help!
