Suddenly, I can't use Navicat to establish SSH tunnel but I can still use other SSH client to connect. Why?
Apply OS: Windows, macOS, Linux
Apply Navicat Product: Navicat for MySQL, Navicat for PostgreSQL, Navicat for Oracle, Navicat for SQL Server, Navicat for MariaDB, Navicat for MongoDB, Navicat Premium
Apply Navicat Version No.: All
In your Linux server, you can find the following file - sshd_config.
If the parameter "AllowTcpForwarding" is set to the value "no", it will disable the SSH port forwarding. By default, after we installed SSH server, it should be set to "yes".
For this case, we would suggest you to consult with your ISP's network administrator.
