It may happen that a SCN loses connection with the PCN for a long time (more than a day), and as a result, the token used for the connection expires. In this case, in the Dashboard section, a PCN token expired. Log in to the SCN and restore the PCN connection message is displayed.
To restore the SCN to PCN connection:
You need to log into the web interface of the specific SCN that you need to reconnect to the PCN.
After some time, SCN is reconnected to the PCN, and the PCN token expired. Log in to the SCN and restore the PCN connection message is no longer displayed in the Dashboard section.
