Although the remote JobServer is running fine, the following error is displayed when trying to configure the remote JobServer on TAC:
Diagnosis
You could run the Job on that remote JobServer from Studio. The remote JobServer is up and running fine, and no network issues are detected. The ports that are configured are correct.
Solution
This problem can be due to a simple configuration issue that occurs when there is a trailing space after the port number is configured on TAC. For example, the command port could be set to "8100 " but you cannot determine this just by looking at the configuration.
To resolve this issue, ensure that there are no extra spaces after entering the port numbers while configuring the JobServer on TAC, then save.
