Error on Self-Portal on any browser

Hi,

Suddenly our users started to "loss" the Self-Portal to submit tickets.
We tried several things like updating SDP (now running last version 11.3 Build 11309), Java updates, browser updates, theme change... nothing worked. I can still login myself as a tech and SDP works as usual to me,

Can anyone help? It was hard to change the minds of our employees to use a ticket system, and now it's not working! :/
