Hi Pavan,


I haven't tried that using ip address but yeah their is windows defender firewall for sure.I dont know which thing is blocking the port.sometimes the studio get easily connected,sometimes in 2-3 attempts and sometimes it never get connected to the server even if we restart the server and restart the system as well.

Hello Abdul,


Please try using the IP address to connect to the server. Also, please check the logs for the TDV Studio and TDV server to understand more about the error message.

Path for Server logs: [TDV_Server_Install_Dir]/logs/cs_server.log

Path for Studio logs: [TDV_Studio_Install_Dir]/logs/cs_studio.log

Potential reasons for this issue as it seems intermittent could be the below:

- there are any potential threads slowing TDV to a state of non-responsiveness to the connection requests from Studio


- TDV is not responding because memory usage is too high


Thank you.
