MATLAB Connector not running

I am using Matlab Connector on Linux (LinuxMint 19.3 based on Ubuntu 18.04).

When I start MATLAB connector (v 1.4.0.6) and then run command: MATLABConnector status

I always get the message: MATLAB Connector not running.

But MATLAB Connector is fully working

Same message I get when run command: MATLABConnector stop

Any idea what is wrong?

During any action on local Matlab Drive folder (ceating folder and creating file) I get the following messages in command line window:

(exo-open:27873): dbind-WARNING **: 17:59:47.127: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Any response???

I'm sorry to hear that you have been waiting a while for an answer on this, and that MATLABConnector has been causing issues for you. The behaviour you are reporting is not the intended behaviour. May I ask if you still have this issue?

If you do still have this issue, would you mind running a few commands to help narrow down the problem?

First start MATLAB Connector by running the following command in a terminal

MATLABConnector start

Would you then be able to send the results of running the following command in your terminal

pgrep -l MATLABConnector

Next, what is the result of the command

MATLABConnector status

Finally does the command

MATLABConnector toggle

successfully toggle the user interface?

After upgrade to Linux Mint 20.x is everything OK.
