Before launching Envoy, ensure the following firewall ports are open: HTTPS port 443, and 5000, 5001 & 8003 to api.gridmarkets.com. Note that some virus protection software, particularly Kaspersky and Windows Defender, can block Envoy so you may also need to disable them or whitelist gm-envoy.exe locally on port 8090
Ensure you login with your Access Key and NOT your Portal password. You can find your Access Key under the Profile page of the Portal (https://portal.gridmarkets.com/init/member_plugin/profile).
If you cannnot login, then open a shell or command prompt and run telnet api.gridmarkets.com 8003 (or 5000 or 5001) to make sure you can connect.
If you are still having issues then please send your Envoy log (under the Portal View menu) to
