We recommend you troubleshoot and locate network connectivity problems quickly with the
telnet command. For more information, please see Prohibition of Ping Command.
If the verification with telnet found that the network access of the TencentDB instance was good, but an error was reported when you tried to log in to it on the command line in the CVM instance, please see Connection.
If you encounter connection errors, we recommend you use One-Click Connectivity Checker to troubleshoot the problem first and then find the corresponding solution in Troubleshooting Connection Errors according to the check report.
