Symptoms
K2 Studio throwing Error when launching
Diagnoses
When launching K2 Studio in our development servers at the bottom left corner we are getting the message "A connection to the K2 server could not be established."
Resolution
This issue came from incorrect connection strings and ports configured.
After reconfiguring the environment and manually configuring the config files, Connection strings and also the Environment library. (also the workflow server changed to port 5252 from 5555) the issue was resolved.
