Yes, it is possible to sync keys by command line.
In this case, you must log in on senhasegura using the 59022 port with the mt4adm user.
The command to solve the error processing keyring is:
orbit key sync
When this error occurs, it will always appear in the Incidents section of the Orbit Config Manager panel with its description, and this description will contain what needs to be done, including the command I sent here.
I hope this helped! Please feel free to reach out if you have any other questions or concerns.
