in the office I cannot go to register.gotowebinar.com. The message PR_CONNECT_RESET_ERROR always comes in Firefox. In other browsers only the general message appears: "Page cannot be displayed". The problem affects all devices in the office. I deactivated the firewall as a test. Antivirus software is not installed. We have a Lancom router if that could be a reason.
Hi @MathiasK, welcome to the community.
Can you please explain what it is you are trying to accomplish?
