The first step is to obtain license information, as this could be the cause of the login issue. To investigate a potential license problem, retrieve the FlexLM logs to determine if there are issues with the licenses and if the license server can be reached from the Docker containers used by Polyspace Access. The FlexLM logs will contain messages with error codes (e.g., -15 for a connection issue) and timestamps that are useful to track the origin of the problem.
FlexLM server logs are stored in a directory specified during the installation or configuration of the FlexLM license server. The log file is often named something like "lmgrd.log" or "flexlm.log". Additionally, review the MLM.opts file, which is used to enable NNU licenses, to see the list of users who can access Polyspace Access.
If you are unable to identify the problem, you can contact MathWorks support. In your request, provide the aforementioned files (FlexLM logs, MLM.opts, license file). Technical support will also need the Polyspace Access debug files.
To obtain these files, follow the instructions in this article
