you could enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.enterprise_roots.enabled. double-click it and change its value to true and restart firefox once - this will import all custom certificates from the windows trust store into firefox and zscaler might become trusted this way. if this doesn't help either you'd have to get in contact with your it department to inquire how to properly set up the system to work with their network monitoring.

hi, is this happening in a corporate environment? according to your error details your connection is not a direct one to google.com but intercepted by a zscaler network appliance.
Hi, yes - this is happening in a corporate environment. Is there a possibility to solve the problem?

Thanks! This helped.
