Conf.Language(31) (localized: not logged in / login expired)

Error message

Conf.Language(31) (localized: not logged in / login expired)

What it means

CloudChatGPT (kernel/model/cloud_service.go:77) returns errors.New(Conf.Language(31)) — the localized 'not logged in / login expired' message — when the cloud AI endpoint responds HTTP 401. It also calls invalidUser(), which clears the cached account, so the next cloud call will see no user. This is an auth-state error, not a network error.

Solutions

1. Log in again (Settings - Account) to refresh the cloud token, then retry the AI chat
2. After catching this error, note that invalidUser() already cleared the cached user; re-fetch the account instead of retrying with the old token
3. Check subscription status if the account is valid but the plan no longer covers AI features
4. In code, detect the localized message or better check user == nil before calling CloudChatGPT and prompt login first

Example fix

// before
reply, stop, err := model.CloudChatGPT(msg, ctx)

// after
if model.Conf.GetUser() == nil {
    ui.promptLogin() // localized Conf.Language(31) equivalent
    return
}
reply, stop, err := model.CloudChatGPT(msg, ctx)
if err != nil && model.Conf.GetUser() == nil { // invalidUser() fired -> 401 path
    ui.promptLogin()
}

if model.Conf.GetUser() == nil {
    ui.promptLogin() // localized Conf.Language(31)
    return
}

user := model.Conf.GetUser()
if user == nil || user.UserToken == "" { promptLogin(); return }

if err != nil && model.Conf.GetUser() == nil { // 401 path cleared the user
    promptLoginThen(func() { retryChat() })
}

When it happens

Trigger: Invoking AI chat while the cloud session token is expired or revoked (HTTP 401 from the ChatGPT proxy endpoint); token invalidated by logging in elsewhere or cloud-side session expiry.

Common situations: Long-lived desktop session whose token aged out; using AI features after the subscription/account became invalid; multiple devices causing token rotation.
