Browser now 'Refuses to connect'?

@Qbert

It is Apache2 failing to restart due to letsencrypt not having a certificate filed.

Regrettably, I am certain I caused this problem by choosing the option for ‘testing’ by thinking this would remain until manually changed. (I left a comment on the UCS blog for UCS with letsencrypt asking how to run UCS as a true ‘home’ Lan only system and never got a response), So I went ahead, tried it in ‘test’, and it worked; at that point.

2. Do I remove let’s encrypt for now? If so, could I have some aid, please, as I cannot seem to find any pages on how to do this?

I finally came across this discussion which provided the command univention-app remove letsencrypt

I have removed Letsencrypt then restarted the Apache 2 server with invoke-rc.d apache2 restart.
I now have access again
