All,

For my collaborator to work from home I have eramba setup behind the firewall (OPNSense) and use the Web application Firewall , I create a virtual external server call [extramba.company.net](http://extramba.company.net) (public) reachable over HTTPS, only persons with a client cert can enter. on the backside I setup eramba with plain http. internally eramba works fine.

so from outside with HTTPS to my WAF and intern from WAF to eramba by HTTP

don’t understand why i can see all the screens but updating gives me a grey screen and error in the browser console

From outside I can login, see screens but as soon as I add something and save the screen turn grey  
and the browser dev console gives me the following error:  
jquery-3.6.0.min.js:2  
Mixed Content: The page at ‘h t t p s://extramba.company.net/security-services’ was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint ‘h t t p://eramba.company.net/security-services?advanced\_filter=1&advanced\_filter\_id=17&\_=1711660150265’. This request has been blocked; the content must be served over HTTPS.

Can someone help me please

thanks

Wim

This is happening to me now as well. It started after I upgraded to version 3.26.0. What was the fix for this? I should also mention, that my installation is NOT behind a web application firewall.
