Hi  
I have installed remote docker instance of **BitwardenRS** on a remote computer with vpn, ssh connection. When I am using browser app works correctly, when I am trying to connect with a **Bitwarden client** ( [https://bitwarden.com/download/](https://bitwarden.com/download/) ) i receive Failed to fetch + ERR\_CERT\_AUTHORITY\_INVALID.

I am using self signed keys and certs as bellow:  
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 100 -nodes

In a client I indicate the same URL as I use in a browser.  
Please help to configure it propertly in order to start using client.

regards

Hello @phaladyj

We suggest to use a reverse-proxy for ssl-offloading, because reverse proxy are better in handling SSL.  
Also checkout some of the updated/new wiki articles:
