Wi-Fi troubleshooting

When a send fails, Lilo shows a short message. Under the message is a code, a short word with an underscore. Find your code below.

First check the basics:

1. The machine is on and awake.
2. It is on a 2.4 GHz network, the same network as your computer. Read Set up Wi-Fi sending.
3. Nothing else is sending to it.

Codes#

machine_unreachable#

"Machine unreachable." Lilo cannot connect at all. The machine is off, asleep, on a different network or has a new address. Do this: turn the machine on, check its Wi-Fi, press Scan network again.

machine_timeout#

"Request to machine timed out." The machine did not answer in time. Do this: wake the machine, move closer to the router and try again.

device_busy#

"The machine is busy with another transfer." Another send is in progress. Do this: wait a minute, or restart the machine.

delivery_unknown#

"Delivery could not be confirmed. Check the file on the device before sending again." The file may have arrived, but the machine did not confirm. Do this: look in the machine's file list before you send again. Sending twice could make a copy.

identity_changed#

"The device identity changed. Scan again and select the intended machine." The address now belongs to a different device. Do this: scan again and save the right machine.

unsupported_operation#

"This device does not support that operation." The machine cannot do what Lilo asked, like listing storage. Do this: use another way, such as a USB stick.

file_exists#

"A file with this name exists. Confirm replacement before sending." Do this: rename the project, or confirm the replacement.

protocol_error#

"Protocol error." The machine answered in a way Lilo did not expect. Do this: update Lilo and the machine's software, then try again. If it keeps happening, report a bug.

machine_rejected#

"Machine rejected the request (machine error code N)." The machine understood and said no. Do this: read the number on the machine's screen. Check its manual. Often the file is too complex or the machine is in a mode that does not accept designs.

file_too_large#

"Design is N bytes but the machine accepts at most N bytes." Do this: make the design smaller or use fewer stitches. Choose Standard quality. Read Standard or Premium.

insufficient_storage#

"Not enough free memory on the machine." Do this: delete old designs from the machine's memory.

unsupported_format#

"Unsupported design format; this machine accepts ..." Do this: export a format the machine accepts. Read File formats.

upload_failed#

"Upload rejected with HTTP status N." The upload was refused part-way. Do this: try again. If it repeats, restart the machine and Lilo.

pairing_required#

"Machine requires pairing." The machine wants to approve this computer first. A hint says what to press on the machine. Do this: follow the hint on the machine's screen, then send again.

invalid_ip#

"Is not an IP address." The address you typed is wrong. Do this: type four numbers separated by dots, like 192.168.1.50.

missing_ip#

An address is needed to test or send. Do this: choose a machine first.

missing_filename#

A file name is required. Do this: give your project a name in the top bar.

cancelled#

"Transfer cancelled." You (or something else) stopped the send. Send again if you want it.

updating#

"Bridge is updating." Lilo is installing an update. Do this: wait until it restarts.

unauthorized#

"Missing or invalid API token." The window and Lilo's built-in connection service lost touch. Do this: restart Lilo.

not_found#

The thing Lilo asked about (a saved machine or a transfer) does not exist any more. Do this: refresh the Machines list.

internal_error#

Something went wrong inside Lilo. Do this: open Lilo Link, then Logs, and report a bug with the log text.

Less common codes#

These come from Lilo's built-in connection service. You will rarely see them. Most need only a retry or a restart.

ip_not_local#

Lilo refuses to contact an address that is not on your home or office network. Do this: use the address shown on the machine's own network screen. It usually starts with 192.168 or 10.

discovery_running#

A network scan is already running. Do this: wait for it to finish.

queue_full#

The send queue is full. Do this: wait for the current sends to finish, then try again.

previous_delivery_unknown#

An earlier send to this machine was never confirmed. Do this: check the machine's file list, resolve that send first, then send again.

not_cancellable#

Only a send that is queued or waiting can be cancelled. Do this: wait for it to end.

not_uncertain#

This send does not need a confirmation. Do this: nothing. Refresh the Logs page.

empty_body#

The file to send was empty. Do this: export the design again and check it has stitches.

invalid_filename#

The file name has a folder or odd characters in it. Do this: rename the project with letters and numbers only.

confirmation_required#

Deleting a file from a machine needs your confirmation. Do this: confirm in Lilo Link.

identity_required#

Lilo must read the machine's status before it deletes a file. Do this: press Test on the machine first.

pairing_in_progress#

Another pairing request is waiting for a decision. Do this: wait a moment and try again.

pairing_origin_mismatch#

A pairing request belongs to a different source. Do this: start the pairing again from Lilo.

origin_required#

Pairing only works from a web page. Do this: read the token in Lilo Link, Settings.

origin_not_allowed#

The web page asking to connect is not on the allowed list. Do this: only allow sites you trust.

invalid_origin#

A web address was not in the right shape. Do this: use a full address, like https://example.com.

Still stuck?#

Use a USB stick while you sort it out. Your design is safe.
