Razer Sila configuration Issues

Hi. Sila is no longer covered by support and I've found 2 issues: - I cannot login using the app, I think that's the related to the expiration date in the certificate, I've tried with two different Android devices without luck, I always get the same error connecting to the server. - Using the web UI is not possible 100% as several config options opened a black screen, for example removing a device in QoS. I've tried with several browsers without luck. Maybe is possibe to renew or change the certificate, I suppose that it would require SSH access but this is no possible or at least not covered. Any help?
