Nextcloudpi issues

I have a lot of problems with my Raspberry and nextcloudpi. After doing an update for the first time I won’t get access to nextcloudpi.local:4443 anymore. Seems like the update breaks something. Moreover I can’t get letsencrypt working. After updating the PI I can still access via ssh and as soon I start to activate letsencrypt there it gives me error line 62 no such file or directory.
