Any idea why this happens to me?
Hi,
seems you always get the following certificate name back jako2009.dynu.net but it dosn’t mach to the website you are trying to open
SSL: certificate subject name (jako2009.dynu.net) does not match target host name 'download.webmin.com'
for sure this doesn’t match and a SSL error is the logical consequence. But this is out of our support as DietPi did not mange one of targeted websites
is jako2009.dynu.net somehow known to you?
Yes this is the dyndns I use to get access from outside home my Odroid.
Any idea why this happpens?
do you use any own DNS Server like PiHole?
You nailed, the problem was Pihole…
…after I disabled it worked like a charm…
Thanks!!! 
yap you would need to find out why PiHole was resolving all request to your own privat DDNS.
I have set on my router instead of the DNS the IP of the Odroid so every device on my network it is under PiHole…
…maybe this is why…
I am not that expert in networks or linux…
well I don’t think that this has something to do with it. I guess that’s more a setting in PiHole that all DNS request are answered with same address of your DDNS. You cold perform a nslookup to see what the answer of your DNS Server/Pihole would be if you try to resolve a DNS name.
Hi sorry for taking so long to reply,
when I do a nslookup with pihole on,
the reply es like this:
nslookup es.wikipedia.org
Server: 127.0.0.1
Address: 127.0.0.1#53
Name: es.wikipedia.org
Address: 192.168.1.25
If I disable pihole I get this:
nslookup es.wikipedia.org
Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
es.wikipedia.org canonical name = dyna.wikimedia.org.
Name: dyna.wikimedia.org
Address: 91.198.174.192
I don’t know if I did something wrong setting up pihole, but I followed the guide for dietpi.
Something is wrong with the Pihole.
Configure your router to use a different nameserver for the hosts of the lan.
Reset pihole to defaults.
Configure Pihole and test it with one host only.
When you are satisfied with it, switch back the settings in router to use Pihole.
trendy
this only helps if the router is playing DHCP server as well.

what is this IP 192.168.1.25 about? is this your internet router? Which Upstream DNS server you configured in PiHole? Can you check pihole -t. It should display Pihole log and you can watch what PiHole is doing on your DNS request. Probably logging would need to be activated >> pihole logging on
Which is the default for all home and soho routers
well I need to use PiHole as DHCP Server because my Router (ISP device) did not support changing local DNS Server.
