I have some problems setting up certificates, but before I ask a specific question, I have a several general ones:
Background:
I use a fritz-box 7390 router behind a cable modem.
Behind this fritz-box there are both two raspberry pies (one of them running owncloud) and a Synology NAS.
I have set up a myfritz-account named vi_xxx.myfritz.net (with xxx being a longer string), for it to be accessable from outside.
-
I understand that there is no possibility to get a Letsencrypt certificate for the vi_xxx.myfritz.net-domain, for there are restrictions as to the number of certificates in a domain and “myfritz.net” is already used by too many (naturally). Is that correct?
-
I therefore have set up a domain via the “Domain Offensive” (do.de): koerber-escheburg.de which is also dynmic via do.de’s “flexDNS” service. For this I’d like to a certificate from Letsencrypt.
-
In order to access my owncloud and my synology etc., do I need separate certificates, or can I use one for “koerber-escheburg.de” and install it on the different systems?
-
The synology brings an assistant for letsencrypt-certificates. Can I use that and afterwards export and import the certificate into the owncloud as well? They seem to use different formats, though.
-
I have tried to set up a certificate via the raspberry for the owncloud, but do always experience great difficulties. First of all, the system hangs for a long time at “installing python”. Is that normal?
Please fill out the fields below so we can help you better.
My domain is: koerber-escheburg.de
I ran this command:
It produced this output:
My web server is (include version): There are several. On the raspberry, it is nginx. The Synonoly has a different one.
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): yes, to the raspberry running owncloud
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
