If you are in a hurry, run through this quick checklist:

: Add the AnyDesk folder (typically in Program Files (x86) ) to your antivirus exclusion list to prevent it from blocking network traffic.

Sometimes the problem isn't on your end at all. AnyDesk relies on central servers to handshake connections. If those servers go down, nobody can connect.

AnyDesk runs as a background service on your computer. If this service crashes or is stopped manually, the software will open but cannot connect to the network.

Using an old version of AnyDesk can cause protocol mismatches, preventing you from connecting to devices running newer versions.
