Lost connection

Hi there, not sure how the last user end up with the debugging; the issue seems so similar with mine, so I decided not to open another post;

Bottom line is:
I've installed projeqtor on my web server in the first days of June;
managed the install, I used all the regular installations path, etc;
Setup a project, tasks, etc, everything seems to work fine;
Except that, 2 days later I've accessed the projeqtor remotely from work; logged in, 20 seconds after that connection got lost; tried several time, the same result.
I was thinking is the net connection - however all other web software were working normally; projeqtor was setup to localhost - even from the installation didn't connected to the static IP of the server; when I change the config file of projeqtor from 127.0.0.1 to the static IP the software cannot be reached.
Today I was working from home, internal network, projeqtor did the job like a charm; when switching to internet (separate connection) the same behaviour ! every instance gets disconnected in a matter of 20-30 seconds. Remember me checkbox didn't helped.

I've tried several things, creating a projeqtor user in mysql with all priviledges, edited the mysqld configuration file ....commenting # the line bind_address = 127.0.0.1, but no fix so far. So ? what else can I try ?
