Hi,
many thanks for your message. According the error, your system is trying to connect to http://localhost:9982/hosting/capabilities
can you check LISTEN ports
ss -tulpn | grep LISTEN
Thank you for the fast response.
I can call the page
http://localhost:9982/hosting/capabilities
it shows a lot of information.
ss -tulpn | grep LISTEN
shows a lot of ports, so I used
ss -tulpn | grep LISTEN | grep 9982
and I got:
tcp LISTEN 0 64 *:9982 *:* users:(("loolwsd",pid=10547,fd=18))
So I think, the adress is reachable, I have no clue, why fastcgi says “fails to open the Stream”
ok it took me a while to get a x86 system up and running but finally it’s working for me. Can you check following on nextcloud
Go to
- Settings
- Administration
- Collabora Online Development Edition
- check “Use your own server”
- enter “http://<your_ip>:9982”
should looks like this
now I’m able to open documents
Hi,
I had to sleep and work a liitle bit in meantime.
I am using the nextcloud collabora CODE-Server-App.
I tried to activate the first menu point “own server” with the following adress (btw.: the IP is the correct one of the localhost): http://192.168.178.80:9982
The server was accepted with a green checkmark, but when i tried to edit an document, the screen remained black. That a little less than before, when the screen went grey and showed the menu-headline.
I mentioned that the “own server” is only accepted, when i startet the built-in CODE-server before.
Thank you for your help!
I just found the origin of the problem and the solution:
In the lighty config-file
/etc/lighttpd/lighttpd.conf
in the section
server.http-parseopts = (
"header-strict" => "enable",# default
"host-strict" => "enable",# default
"host-normalize" => "enable",# default
"url-normalize-unreserved"=> "enable",# recommended highly
"url-normalize-required" => "disable",# recommended
"url-ctrls-reject" => "enable",# recommended
"url-path-2f-decode" => "enable",# recommended highly (unless breaks app)
#"url-path-2f-reject" => "enable",
"url-path-dotseg-remove" => "enable",# recommended highly (unless breaks app)
#"url-path-dotseg-reject" => "enable",
#"url-query-20-plus" => "enable",# consistency in query string
)
the following keyword
"url-normalize-required" => "disable",# recommended
must to be disabled.
Maybe that information maybe helpful for anybody 
strange for me this is working with default web server settings
I have tried this, but it does not work for me, I have been testing for several days … there is a docker with collabora-code, I have it working, in the Nextcloud configuration it makes a green check, but when opening the file, the screen remains blank.
There is no easy way to configure collaborate with dietpi? collabora / onlyoffice / ms Office online
Thanks
This not work on Arm64? it would be great for raspberry, because I think there is no other alternative.
for me it is working well on RPi4B 64bit
The fix (config change) should not required anymore as the underlying bug has been solved in the Debian package. At least when it’s the same underlying issue that caused logout to fail with Lighttpd and that was fixed with the same config change 
.
On my test it is working OOTB, without any fix 
and your Colabora is installed on a docker? or how do you have it installed?
I will try again, I would like to leave it working, although it consumes a lot of Ram, it is very useful.
Thank you!
on my test I simply activated it inside NextCloud without any docker instance.
I just installed again collaborates from the application manager.
the problem is this, when opening a document it appears like this … nothing else, no error messages to correct the problem.
I don’t know why it doesn’t work for me.
There might be one main difference. On my test, I explicitly set my own Collabora Online-server and did not use the built-in one.
This way I’m able to open documents
What is your current configuration?
finally I decided on a local installation, to exclude possible docker problems, but with the same result … I don’t know what else to try, I would like to have an office package on the raspberry but I am not able
There is no crash log in nextcloud
Let me copy myself as already written above

Seen your 2nd screen print
Hello,
i know this thread is really old, but maybe it could be usefull for someone else.
Installed a Debian AMD64 netinstall with ssh server and system-tools.
Run the dietpi-script
Installed nextcloud with lighttpd server through “dietpi-software”
Installed “Nextcloud office” and “Collabora Code server” inside of nextcloud.
“Try again later” when trying to open a document or new one.
Searching for 2 days, tried a lot of possibilities and ports and and and…
Searched for “dietpi nextcloud collabora”, found this site, changed
"url-normalize-required" => "disable",
and now, it is running.
To tell the truth: i do not understand what this parameter is doing 
Greetings
Which Debian version are you using? This was indeed a bug in Lighttpd back in 2019 in Debian Buster (which is already EOL) with Lighttpd 1.4.53, but fixed in Lighttpd 1.4.55. Buster backports and of course Bullseye and Bookworm contain newer Lighttpd versions with this fixed. And the fix has been even patched into regular Buster repo in 2020. So this should really not be an issue anymore since 3.5 years, if one did any apt upgrade since then.

I had same problem 2 weeks ago with my Z83_II (testing-“server”), but that is running “Trixie” and has 2 GB RAM, so i thought that could be a problem of to less memory (it was really swapping a lot while collaborate server was started in background).
Now i got the IGEL M350C with 4 GB and ran into the same problem (which was solved by this trick here) 
I really just installed a pure debian without desktop, just ssh-server and systemtools from the choices i had while installing.
I started conversion with dietpi-script, rebootet and installed nextcloud+lighttpd, samba and pi-hole.
