How to fix NetCologne not working
NetCologne 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 netcologne.de over your own connection, right now. Nothing is sent to us or stored.
Reload and restart
Reload the page (Ctrl+F5, or Cmd+Shift+R on a Mac), or fully close the app and open it again.
Try another connection
Switch between Wi-Fi and mobile data. If it works on one and not the other, the problem is your network, not NetCologne.
Update the app
Install the latest version from the App Store or Google Play. Old versions can stop connecting after a server-side change.
While NetCologne is down: what to use instead
- Mobile hotspot Use a phone with data from another provider as a hotspot when your home internet line is out.
- Public Wi-Fi A library, office, hotel, or cafe connection helps if you need to work before the fixed line returns.
- Mobile calls and SMS If the landline or internet phone will not register, use a mobile phone for urgent calls and two-factor codes.
- Customer phone support If the website or customer area will not load, call support from a mobile phone and keep your customer details nearby.

Tip: NetCologne doesn't list a public status page that we know of, so its help centre and the report chart on this page are the best places to check.
How we track NetCologne
The status on this page comes from user-submitted problem reports for NetCologne, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for NetCologne, 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. NetCologne 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.
