Ubuntu 20.04 - Web login / Thinlinc Client

Hi!

I just install server 4.16.o on Ubuntu 20.04 and try to Thinlinc client or Web Access and ever show this error when I try with user “creative”

ThinLinc login failed.
(No agent server was available)

I get this but VMSAgent is running

systemctl status vsmagent

And VSMServer is runing too

systemctl status vsmserver

From tlwebaccess.log

Could you provide more log output from vsmserver.log, and also include the user session log from
/var/opt/thinlinc/sessions//last/xinit.log ?

Kind regards,
