Issue Description
On checking, uploading, or downloading a license Archicad' s License Manager Tool gives an error Connection to the server could not be established.
Solution
The "Can't connect to the server" error in the Archicad License Manager Tool (LMT) typically occurs due to network or software issues preventing the tool from accessing Graphisoft's licensing servers. Here are some common reasons and troubleshooting steps:
Internet Connection Issues
- Ensure you have a stable internet connection.
- Verify that your firewall or network is not blocking internet access for the License Manager Tool.
- Try switching to a different network, such as a mobile hotspot, to see if it resolves the issue.
Firewall or Antivirus Interference
- Sometimes, firewalls or antivirus software can block the License Manager Tool from connecting to the server. Check if any security software is blocking the application and temporarily disable them to test the connection.
- Ensure the following services are allowed through the firewall:
Licensing Port Blocked
- The tool uses certain ports to connect to the server. Ensure these ports aren't blocked by your router or IT network settings.
VPN Connection
- If you're using a VPN, it might interfere with the License Manager Tool's ability to connect to the server. Try disabling the VPN and connecting again.
Outdated License Manager Tool
- Ensure you're using the latest version of the License Manager Tool. You can download updates from the Graphisoft website. Sometimes older versions may not be compatible with current servers.
Server Downtime
- It’s possible that Graphisoft's licensing servers are temporarily down for maintenance or facing connectivity issues. You can check Graphisoft's official channels to confirm if there are any ongoing server problems.
