-If you're using TLS for your other [[server:|Synchronet servers (e.g. web, mail, ftp, etc.)]], you may also need to rename/move or delete your ''[[dir:ctrl]]/ssl.cert'' file.
-These files (''cryptlib.key'' and ''ssl.cert'') are encrypted with the Synchronet //system password//, so if the system password is changed then these files must also be regenerated. The files are automatically recreated by //sbbs// upon startup if they do not already exist.
