This error message indicates that Maple is having problems connecting to the kernel over a local host connection.
Computer-based causes and solutions
- The computer needs to be restarted.
- The operating system needs to be updated (patched) or upgraded (to a newer version).
- Disable any and all security software, including active scanning.
Maple-based causes and solutions (contact firstname.lastname@example.org for more information)
- Maple needs to be updated.
- Maple is corrupted, and should be reinstalled from a fresh download link.
- The "connection type" which Maple uses to connect to the kernel over the localhost connection may need to be manually changed in the initialization file.
Things to check
- Is Maple properly activated?
(Please note on some Linux distributions you may need to install 32-bit compatibility libraries to activate) .
- Does the command-line interface (CLI) of Maple work?
- If the CLI works, likely the installation is good and the connection is bad. On the other hand, if the CLI doesn't work, the installation is likely corrupted.
