Troubleshooting
Problem
Unable to connect to a TM1 server from Planning Analytics Workspace (PAW) for modelling as a loading bar appears indefinitely below the TM1 server.
A connection could not be established from PAW however the same model was accessible via Architect.
Symptom
In the browser HAR trace, we see an entry:
GET http://<admin_server_name>/prism/harmony/gridservice/api/v1/Servers('<TM1_server>')/Login
with the following error:
{"error":{"code":"EXECUTION_ERROR","message":"org.apache.http.conn.ConnectTimeoutException: Connect to <ip_address>:52670 [/<ip_address>] failed: connect timed out"}}
Cause
The issue is due to strict Windows Firewall rules that blocked the HTTPPortNumber, which the TM1 Server uses to listen for incoming HTTP(S) requests.
Resolving The Problem
To resolve the issue, create an inbound firewall rule for the affected TM1 server's HTTPPortNumber.
The affected port number can be found in the models tm1s.cfg file or from the browser HAR trace.
Example: The blocked port number "52670" is mentioned in the following HAR trace error:
{"error":{"code":"EXECUTION_ERROR","message":"org.apache.http.conn.ConnectTimeoutException: Connect to <ip_address>:52670 [/<ip_address>] failed: connect timed out"}}
