Rustdesk: password does not match, but does not ask to enter it manually when connecting to client.

Hello, I don't know if it was a coincidence, but after I had a problem in Ubuntu 24.04, I ran out of desk, then I repaired. the next day I was going to connect to a client and he indicated a connection error, password does not match, but he did not ask for the password, so check forget password and the problem persists. Uninstall ruskdesk and reinstall clean and the problem persists.

Also try to connect me from another PC to my computer and you cannot connect. I have rustdesk hosted.

However, I can connect to the client who wants to connect from another PC and even from a cell phone.

thankyou for help

Start with the failed connection path in src/client.rs, especially the logged “Key mismatch(1)” at the reported session attempts. Read the related session and UI handling in src/flutter.rs and src/ui_interface.rs, using the Ubuntu 24.04 and Rust 1.4.0 details as the reproduction context. Done means the cause of the missing password prompt and failed connection is identified and the affected behavior is verified.
