FACT(s) (Environment):
UNIX
Progress 9.x
OpenEdge 10.x
SYMPTOM(s):
Error in SOAP request execution: SessionPool : NoAvailableSessions[Could not connect to the AppServer: General Error: Connection timed out: connect. (7203)] (10926)
SessionPool : NoAvailableSessions[Could not connect to the AppServer].
Could not connect to the AppServer: <message text>. (7203)
Could not connect to the AppServer: The operation has timed out. (7203)
Client connect to AppServer (A), which connects to AppServer (B) on behalf of client.
By changing code so client's request is handled by AppServer (A) only, it is sucessful.
AIA status shows connection OK.
CAUSE:
Firewall was blocking the ports between the two AppServers.
FIX:
Open the Firewall ports between the two AppServers.
