fastcgi-problem with dietpi x86 lighttpd nextcloud collabora [solved]

[rick110]

Hi,

I am running on dietpi x86 and installed LLMP and nextcloud. In nextcloud I activated the collabora CODE - Server.

Formerly I used Arch Linux and nextcloud worked with the LLMP-stack pretty well, even the collabora-server.

When I try to work with a document in collabora there is no connection to the collabora-server. The workspace remains empty.

The lighttpd error.log shows the following entry:

Code: Select all

(mod_fastcgi.c.421) FastCGI-stderr: PHP message: PHP Warning:  file_get_contents(http://localhost:9982/hosting/capabilities): failed to open stream: HTTP request failed! in /var/www/nextcloud/apps/richdocumentscode/proxy.php on line 208

Has anyone an idea how to fix it?

Thank you in advance

Rick

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

Code: Select all

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.

Code: Select all

ss -tulpn | grep LISTEN

shows a lot of ports, so I used

Code: Select all

ss -tulpn | grep LISTEN | grep 9982

and I got:

Code: Select all

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

1. Settings
2. Administration
3. Collabora Online Development Edition
4. check "Use your own server"
5. 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

Code: Select all

/etc/lighttpd/lighttpd.conf

in the section

Code: Select all

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

Code: Select all

"url-normalize-required"  => "disable",# recommended

must to be disabled.

Maybe that information maybe helpful for anybody
