Error message

Failed to store credentials

What it means

Same store path as error 114, but this variant is thrown when secret_password_store_sync returns false with no GError set — the write was reported unsuccessful without a descriptive error — so a generic InteropException with code -1 is thrown.

Solutions

1. Retry the store once — transient daemon states can cause a silent false return
2. Check keyring daemon logs (journalctl --user -u gnome-keyring) for the underlying failure
3. Ensure you are using a standard Secret Service implementation (gnome-keyring/kwallet) and it is healthy
4. Catch InteropException with Code == -1 to detect the no-detail failure case and surface a generic message

Example fix

// before
collection.AddOrUpdate(service, account, secret); // can throw code -1
// after
try { collection.AddOrUpdate(service, account, secret); }
catch (InteropException ex) when (ex.Code == -1) { RetryWithBackoff(() => collection.AddOrUpdate(service, account, secret)); }

// Silent-failure path: no pre-validation possible; enable retry.
int attempts = 0;

try { collection.AddOrUpdate(s, a, secret); }
catch (InteropException ex) when (ex.Code == -1 && ++attempts < 3) { Thread.Sleep(200 * attempts); retry:; }

When it happens

Trigger: AddOrUpdate where the native call completes without a GError but its bool result is false: daemon-side silent rejection of the store operation.

Common situations: Race with keyring daemon shutdown/restart during the store; unusual daemon implementations (e.g. keepassxc-proxy) returning failure without an error; resource exhaustion inside the daemon.
