The raspberry pi is connected through ethernet to the router and I can check/download updates without any issues.
This is the screen I always get when attempting to install Octoprint:
[Solved] Cannot install Octoprint due to network issues but network is working
[Solved] Cannot install Octoprint due to network issues but network is working
Today I just flashed and updated the latest image of Dietpi on a Raspberry Pi 3B+. Everything went fine but cannot install Octoprint from the software optimized. I get an error like dietpi cannot reach the octoprint gihub repository url but network is correctly working.

@Garret
Thanks for your report. Will check here.
EDIT
Hmm works great here:
Which DNS server do you use? cat /etc/resolv.conf

What happens if you try the above (outside of dietpi-software)?root@VM-Stretch:~# G_CHECK_URL https://github.com/foosel/OctoPrint.git

Re: Cannot install Octoprint due to network issues but network is working
Giving G_CHECK_URL https://github.com/foosel/OctoPrint.git returns the same window I showed you in my first post. For some strange reasons it seems it cannot reach the url.
While giving the cat command I get the dns server of my router which I then set with the google ones (8.8.8.
I tried to reach the repository with the curl command and this was the result:
I don't understand. I tried to install other programs via the software optimized and they installed without any problem.

@Garret
The curl output is expected, host resolution worked fine with the Google DNS.
You can verify again with G_CHECK_URL, I am pretty sure it works as well.
So in this case I would check your routers DNS settings, if it actually serves as DNS server and which uplink DNS server it uses itself. You could then also try to use the configured uplink DNS server from your router directly, perhaps this is/was temporarily or permanently down or faulty.

Re: Cannot install Octoprint due to network issues but network is working
Hmm I tried again this morning but I get always the same window with the same error.
If I connect from my phone to the router via wifi, I can access that url. I have DHCP set up in the router and the google dns as primary and secondary dns. I tried to switch the google dns on my router with the cloudfare (1.1.1.1), rebooted the router and raspberry pi and still get the same error.
That is so weird...

Re: Cannot install Octoprint due to network issues but network is working
Did you verify that the Pi adapts the cloudflare DNS from the router after connecting (via DHCP)?
Note that any DHCP lease in most cases overwrites /etc/resolv.conf. It is a dynamically created file, controlled by resolvconf package which can be triggered by different sources, e.g. DHCP clients.
What you could try as well is use a static IP instead of DHCP and hard code the DNS server there. If the static IP is within the DHCP IP range and as well configured as reserved for the Pi in the router network settings, this should work well in most cases. This is how I do it here
.
Just to be sure, you don't have Pi-hole installed, do you?

Re: Cannot install Octoprint due to network issues but network is working
I (partially 
) solved the problem by installing octoprint manually. It is so weird that when using the dietpi-software it cannot clone the git repository but if I give the command manually it works without any issues. There must be something wrong with the dietpi-software, like it connects using some other network configuration for some reason.
This was the procedure I used on a clean dietpi installation:
Can you suggest an easier way to install it and have it always running when I restart dietpi? And still it would be really nice to have it installed through the software optimized...

@Garret
Can you please try: G_CHECK_URL https://github.com/foosel/OctoPrint.git
So we see if wget and even our wrapper works outside of dietpi-software.

Re: [Solved] Cannot install Octoprint due to network issues but network is working
Hi @MichaIng, thank you a lot for your message. As I said in my previous post, I had already tried that command and gives me back exactly the same error window
But I tried it again this morning and I got the same result. I really don't understand...

Re: [Solved] Cannot install Octoprint due to network issues but network is working
Okay, I have no idea why this fails in your case while it works well in other cases, especially since git clone works fine in your case as well.
You can try the naked: wget --spider https://github.com/foosel/OctoPrint.git
However aside from that to allow you installing OctoPrint via DietPi-Software, please open /DietPi/dietpi/dietpi-software, find the line with https://github.com/foosel/OctoPrint.git and remove the G_CHECK_URL "$INSTALL_URL_ADDRESS" below.
This skips the online check which is not required if you already know that git clone works.
