Try these steps
- 1 Check that your internet or office network works by opening another website or shared folder.
- 2 If you work remotely, connect the VPN first — many business applications only work on the company network.
- 3 Close the application completely and open it again.
- 4 Ask a colleague whether the application works for them. If it fails for everyone, the server may be down.
- 5 Write down the exact error message and the time it happened.
- 6 Restart your computer and try again.
Before you start
Work through the steps in order and stop as soon as the problem is fixed. Never share passwords or verification codes with anyone.
When to contact support
If the application fails for several people, open a High priority ticket with the application name and the error message.
