Titan is a cloud-based software used by car dealers to manage their inventory and business.
There had been some reports where PC’s connected through DrayTek routers experience slow or intermittent Titan connectivity issues.
The issue has been identified as being due to a TCP timeout on web traffic to Titan resulting in connections being closed.
Increasing the TCP www and TCP Syn values helps to resolve this issue.
To do this run the telnet command “portmaptime”
DrayTek> portmaptime ?
PortmapTimeSetting [-<command> <parameter> | … ]
-t <sec> : set TCP protocol session timeout.
-u <sec> : set UDP protocol session timeout.
-i <sec> : set ICMP protocol session timeout.
-w <sec> : set TCP WWW protocol session timeout.
-s <sec> : set TCP SYN protocol session timeout.
-f : flush all portmaps (useful for diagnostics)
-l <List> : List your all setting
Note: this telnet cmd only works when half of the sessions are still available
To check current settings run the command:
— current setting —
TCP www 60
TCP syn 60
Update both TCP www and TCP Syn to 10800 or greater
Note run the command “sys commit” at the end to make the changes permanent
portmaptime -s 86400
portmaptime -w 86400
