Please make sure the "Don't Allocate a pseudo terminal" option is disabled. You can find this option under Properties > SSH.

I checked it, the "Don't Allocate a pseudo terminal" option is disabled by default. The issue is still existed.

Could you post the SSH log file? Depending on your system, log path may vary. The default location for openSSH is usually '/var/log/'.

We will get back to you after analyzing the SSH log file.

I am using Telnet, why you need the SSH log file?

I am sorry for confusion. I thought you are using SSH.

This problem may occur when local echo is disabled. Try the following command to re-enable local echo:

stty echo


If the problem perists, please send us the following information:

1. What is the result of the following command?

stty -a

2. A screenshot of the problem.

Hi,

When this issue happened, could not enter any character on the terminal, how to run "stty echo" or "stty -a"? Do you mean run the other session tab with the same windows?

On the other session tab, the following is the result of "stty -a":
speed 9600 baud; line = 0;
rows = 38; columns = 96
min = 4; time = 0;
intr = ^C; quit = ^\; erase = ^H; kill = ^U
eof = ^D; eol = ^@; eol2 <undef>; swtch <undef>
stop = ^S; start = ^Q; susp <undef>; dsusp <undef>
werase <undef>; lnext <undef>
