Hi Subrata ,
The error suggests an issue with trial activation for RStudio Connect. Ensure your server has internet access to connect to the RStudio trial activation server. Confirm that the specified URL (http://apps.rstudio.com/trial-activation/) is accessible from your server. Check for any firewall or network restrictions that might be blocking the connection. If the issue persists, reach out to RStudio support for assistance. Additionally, make sure you are using the correct licensing and that your server environment aligns with the requirements specified by RStudio Connect. Regards, Saravanan Ganesan.
