Hello,
Does it happens consistently?
It looks like it is the toad try to connect to server but failed.
1> Does your side and TIC server side both could connect to the DB you use?
2> You could check in path like:
TIC servicelog file: C:\ProgramData\Quest Software\Toad Intelligence Central\logs
Toad.log： C:\Users\Administrator\AppData\Roaming\Quest Software\Toad Data Point 5.0
3> If you could not find out why, you could create a support case.
Regards
Lyla Su
