About Signal problems

Signal problems can show up as messages that do not send, calls that fail or a registration code that does not arrive. Check the Signal status page first, then test whether the problem stays when you switch between Wi-Fi and mobile data. Registration needs an SMS or voice code to the phone number, so poor mobile reception can delay it.

Official information

Signal official status page (verified )

Our check and Signal's own status page can disagree. We test from one location and read only the homepage response. The provider reports what it knows about its own systems, such as sign-in, apps or single regions. A site can answer our check while one feature is broken, and a regional problem can affect one location but not another.

How this check works

  • One measurement location (single-self-hosted-probe), not a worldwide test.
  • We read only the response headers of the HTTPS homepage; page content and features are not tested.
  • We follow at most 5 HTTPS redirects and check every new address again.
  • The whole check stops after 10 seconds.
  • Results are reused for 60 seconds; this page refreshes its saved check at most every 10 minutes.

Typical Signal problems

An editorial list of typical problems, not based on live user reports.

  • Messages do not send If Signal messages stay without a delivery tick, the network may be blocking Signal's servers, so compare Wi-Fi with mobile data. Guide: ERR_CONNECTION_TIMED_OUT
  • Registration code does not arrive Signal sends registration codes by SMS or voice call, so check reception and request a voice call if the SMS does not arrive.
  • Calls drop or do not connect Signal calls can drop when the device switches networks during the call, so stay on one connection while testing. Guide: ERR_NETWORK_CHANGED
  • Signal Desktop stops receiving Signal Desktop is linked to your phone, so if it stops receiving messages, relink it from the linked devices menu in the phone app.
  • Website cannot be found If signal.org cannot be found on a network, that network's DNS may be filtering it, so test with mobile data. Guide: ERR_NAME_NOT_RESOLVED

General fixes: Messaging

  1. Read the delivery marks Messaging apps show whether a message has left your device. A clock or a single mark means it is still waiting for your connection or the other person's.
  2. Allow background data Battery and data savers on phones can pause messaging apps in the background. Allow background data for the app so messages arrive on time.
  3. Relink desktop and web apps Desktop and web versions are linked to your phone. If they stop updating, unlink them and link them again from the phone app.
  4. Free up storage Photos, videos and voice messages need free space on the device. A full phone can make downloads and backups fail.
