<![CDATA[HELP - OpenVPN 2.5.9]]>Hello everyone,
I am experiencing an authentication issue with OpenVPN 2.5.9.
Has the SSO been modified?
Thank you in advance.

Cloudron version 10.0.5
OpenVPN 2.13.0
I stuck with this version because updating to the next one really messed up my VPN connections.

scope=openid profile email[espace]

I created a patched Docker image for the OpenVPN 2.13.0 application by modifying the scope generation to use .trim(), thereby removing that space.
After redeploying the application with this image, the scope is generated correctly:

scope=openid profile email

OIDC authentication and access to the OpenVPN interface are working again, without modifying existing VPN configurations.

I think this was fixed. Which version of Cloudron are you on and which version of the VPN package?
