[Nix-dev] svn.nixos.org uses an invalid security certificate

[Tony White]

Hi everyone,
Maybe someone knows if there is a solution to firefox providing this
message when visiting svn.nixos.org :

svn.nixos.org uses an invalid security certificate.
The certificate is not trusted because the issuer certificate is unknown.
(Error code: sec_error_unknown_issuer)

I know I can override it but is this a known issue and does it just
need it's ssl certificate regenerating server side?

Thanks,
Tony
