ERR_SSL_SE​RVER_CERT_​BAD_FORMAT​(-167) under Linux

Hello,

I start using Matlab on Linux for work but often when I start Simulink, the toolbar is replaced with this message:

And I must restart Matlab until it disapear. Also sometime the toolbar, when it is here, does not answer to click anymore. It generally happens while a simulation is running.

I'm connected to internet and I don't have this issue on Windows. I tried to open the ports, but no effect:

~ sudo ufw status 
État : actif

4626 (v6)                  ALLOW       Anywhere (v6)   

I'm using Matlab R2019b.

Does anyone know why it happens and how to fix it?

Thanks, have a nice day.

This also happens to me all the time.

Same happening me too!

[Hasan Sener]

Still the problem goes on!!!!!

Happens to me in R2019b, 100% of the time as far as I can tell. Considering that R2019b takes about five minutes or more to restart, I never considered retrying repeatedly to even be an option.

It seems the internet access is not friendly with MATLAB. I have problems like this when I was in China. I suggest to use a VPN or some other kind of proxy on your computer or rent a VPS in some places like USA. Best, Bo
