Troubleshooting

How to fix Graubündner Kantonalbank not working

Graubündner Kantonalbank is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:

Your browser tries to reach gkb.ch over your own connection, right now. Nothing is sent to us or stored.

  1. Try the sign-in again

    A dropped connection or a timed-out session can throw a login error that looks permanent; close the tab or app, wait a minute, then sign in again from the same device. Note the exact wording in the message.

  2. Use the browser login instead

    The app and the eBanking login at gkb.ch travel different paths, so a phone that fails may still work on a laptop. Open the site in a clean browser window and sign in with the same credentials. If that works, the fault sits on your device.

  3. Restart the app and clear its cache

    Force the app closed and start it again after restarting the phone, which clears a stale session or a hung token. On Android, open Settings > Apps, pick the bank's app, then Storage and tap Clear cache; Clear data wipes your saved login, so leave it alone. Check the App Store or Play Store for a pending update before the next attempt.

  4. Read the FAQ, then contact the bank

    The help centre at https://www.gkb.ch/de/service/faq explains how to reach support and what blocks an account after failed logins. Repeated wrong passwords may lock your access, and only the bank can lift that. Have your account details ready when you get through.

While Graubündner Kantonalbank is down: what to use instead

  • Website in a browser Signing in from a laptop gets you to the same accounts and payments when the app will not open or keeps throwing you out.
  • Your physical card Your card pays at the till even when the app is stuck.
  • Phone call to the bank If a transfer cannot wait, or a card needs blocking, the phone line works without the app in front of you.
  • A branch counter For cash or a face to face payment, a branch does the job; you trade a few taps for a short trip.

About

What happens when Graubündner Kantonalbank goes down

Graubündner Kantonalbank is a Swiss cantonal bank based in Chur; private customers and companies across Graubünden rely on it. If e-banking or the mobile app stops responding, you cannot check balances, approve payments, move money between accounts, or view recent transactions; the status at the top of this page comes from user problem reports, and this site does not monitor the service.

Login breaks first. You enter your credentials and the page hangs, or the app kicks you back to the start screen; once you get past that, balances may load with long delays or show old figures, while transfers and QR-bill scans fail or sit as pending. Card payments often keep working because they run on separate systems, so you can still pay in shops even when e-banking is down. The trouble is often partial: one channel fails while another works, and user reports can cluster in Graubünden more than elsewhere because that is the bank's home market.

Questions

Graubündner Kantonalbank FAQ

Is Graubündner Kantonalbank down right now?
The status at the top of this page shows whether problem reports for the service are above their usual level, counted in 15-minute windows over the last 24 hours; it does not test the app or your connection. If the report level is normal, check your side before you assume an outage: switch between Wi-Fi and mobile data, and open the app on another phone or browser. A login that fails on one device but works on another points to your device; a card payment refused in a shop is a separate problem from a failed eBanking login at home.

Why does the GKB Mobile Banking app keep asking me to log in again?
The app drops a session when the phone locks or the connection changes between Wi-Fi and mobile data. That is normal security behavior. Check that battery saving is not closing the app, and update it from the App Store or Google Play if the login loop started after a system update. If the app rejects your password on every device, reset it through the help centre rather than retrying until the account locks.

Why does GKB eBanking reject my QR bill scan?
A QR bill scan fails most often because the camera cannot read the code: glare on the paper or a crease through the QR square will stop the scanner before any payment starts. Type the reference number by hand if the scan keeps failing, and check that the bill is a Swiss QR bill with a readable payment part. If eBanking shows a red warning on the payment form, compare the amount and account details with the paper bill before you approve it.

Why was my GKB card declined at a shop?
A declined card at a terminal can come from the card limit or a blocked card; the shop's terminal losing its connection can look the same. Try a small contactless payment and check the card settings in the app. Call the number on the back of the card if the card is blocked. If the same card works at an ATM but fails in one shop, the terminal is the likely problem.

Does GKB eBanking work when I am outside Switzerland?
You can usually reach eBanking from abroad, but the bank may ask for extra confirmation when it sees a login from an unfamiliar country. Make sure your usual login confirmation method still works while you are away, and use a stable connection rather than a public Wi-Fi network. If the login page loads but the confirmation step fails, contact the help centre before you try again.

How we track Graubündner Kantonalbank

The status on this page comes from user-submitted problem reports for Graubündner Kantonalbank, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Graubündner Kantonalbank, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.

When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. Graubündner Kantonalbank doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
