Summary
HMRC is experiencing maintenance or a temporary outage. This typically resolves within 24 hours. Konfir will automatically email you as soon as HMRC is back up with a secure link to rejoin your verification.
What to do
Try again later - Watch for Konfir’s “service restored” email and use the link to continue with HMRC when it’s available again.
If you’re short on time, skip HMRC and connect Banking and/or Payroll so your verification can still progress. If your verifier only enabled HMRC, you’ll need to wait for HMRC to be back online.
