Hi @CristianSW

Collabora recently changed their docker image. You have to replace “loleaflet” with “browser” and “lool” with “cool” in the reverse configuration, to make it work.

Previous configuration:

Current and working configuration:  
[https://sdk.collaboraonline.com/docs/installation/Proxy\_settings.html#reverse-proxy-settings-in-apache2-config-ssl](https://sdk.collaboraonline.com/docs/installation/Proxy_settings.html#reverse-proxy-settings-in-apache2-config-ssl)
