Nextcloud version (eg, 20.0.5): 21
Operating system and version (eg, Ubuntu 20.04): Raspbian GNU/Linux 10 (buster)
Apache or nginx version (eg, Apache 2.4.25): nginx/1.14.2
PHP version (eg, 7.4): v7.4.15

The issue you are facing:
From administration, check whiteboard config throws errors

Failed to contact Spacedeck API: cURL error 7: Failed to connect to localhost port 9666: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:9666/api/spaces

Spacedeck API is not accessible. cURL error 7: Failed to connect to localhost port 9666: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:9666/api/spaces

From the log:

Having the exact same Problem here.

The problem seems to be that spacedeck.nexe.bin is a x86-64 binary and thus incompatible to the Raspberry Pi 4 using Raspberry Pi OS 64 on ARM64 / aarch64.

sudo file spacedeck.nexe.bin
spacedeck.nexe.bin: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=2f939e828e5332cd3be98272bedfe905c9f029a7, with debug_info, not stripped

@nextcloud Any chance you could provide a ARM64 version of whiteboard_integration?

Best regards
Thomas

Hallo,
wo genau liegt die spacedeck.nexe.bin? Ich habe die App ebenfalls installiert aber finde diese Datei njicht? Ich konnte das whiteboard nur duchr die Installation von spacedeck-open dazu bringen die Fehlermeldung nicht mehr anzuzeigen!?

@mueller

Daniel, pls keep to the language of Threadstarter… and pls post in english only on the int’l part of the forum.

treuss · March 1, 2021, 8:31am

You’ll find spacedeck.nexe.bin in [DATA]/appdata_xxxxxxxxxxxx/spacedeck/

mueller · March 1, 2021, 9:35am

Ok. The file is there, and spacedeck is running:
ps aux| grep spacedeck
root 5849 0.0 0.0 112824 968 pts/0 S+ 10:32 0:00 grep --color=auto spacedeck

But when I start the APP in Nextcloud there are errors:
./spacedeck.nexe.bin: /lib64/libstdc++.so.6: version GLIBCXX_3.4.20' not found (required by ./spacedeck.nexe.bin) ./spacedeck.nexe.bin: /lib64/libstdc++.so.6: version GLIBCXX_3.4.21’ not found (required by ./spacedeck.nexe.bin)
./spacedeck.nexe.bin: /lib64/libstdc++.so.6: version `CXXABI_1.3.9’ not found (required by ./spacedeck.nexe.bin)
And that is the reason why the whiteboard is not working on my centos 7 machine
and gcc version:
gcc -v

I have the same issue, below the error log

Hello the fact is and the solution:You need min. nodejs 10 installed and min. gcc 7.3
then the whiteboard is running.
Test with node -v

node -v

v10.24.0
And with gcc -v
gcc -v

Did you setup your own spacedeck? As in the nextcloud-app node.js is already packaged and the shouldn’t be the need to install node.js at all…

mueller · March 2, 2021, 9:42am

No I use the nextcloud spacedeck. Installed node.js 10 anyway. But as I noe recognize the Whiteboard is at this time real buggy. Now and then instead of my whiteboards there is a registration page of spacedeck showing up:

To buggy to go in production for me

szaimen · March 3, 2021, 12:16am

Great answer, thank you!

chrissooo · March 6, 2021, 8:34am

Hallo @mueller

Thanks for Info. I install gcc 7.3 and now spacedock starts and i can use it. But only when i go in appdata Folder and start its manuell. Its not start automatic.

Is it a problem in the CentOS 7 Selinux, Apache, PHP configuration? I nothing found in audith log. Manuell Start work… Where i can check for errors.

UPDATE: Sorry, it was a selinux Problem. Just do “semanage permissive -a httpd_sys_script_t” and its work now.

Thomas077 · March 17, 2021, 7:00pm

I have the same screen as you, I am using the latest docker image.
However I checked the version of gcc, it is 8.3.0 so should be fine?
Next I checked the version of nodejs, unfortunately it was not installed. However after installation and reboot, still the same nice SpaceDeck screen.
Could you found a solution?

Apitoxine · April 16, 2021, 8:33am

Hi,

I have the same error with Nextcloud 21.0.1 installed on a Synology NAS, any idea on how i can fix this ? I did try to install Node.js 12 from Synology app store.

jupsoleil · June 1, 2021, 8:42am

Hi, I have the same issue. I’m running it in snap on ubuntu LTS 18.04, nextcloud version 21.0.1

jupsoleil · June 23, 2021, 10:11am

I registered the issue at Whiteboard not working in nextcloud snap 21.0.1 · Issue #1768 · nextcloud/nextcloud-snap · GitHub

mjeshurun · September 15, 2021, 11:03am

Same issue for me.
I’m using Nextcloud 21.0.4.1 installed with NextCloudPi on Raspberry Pi 4 4GB running Raspberry Pi OS 64bit with Desktop.
I have Node.js version 14.17.6 and gcc version: 8.3.0.
Nevertheless, when I try to open a whiteboard file within the Nextcloud Files app I see this error message:
Impossible to load Spacedeck whiteboard "cURL error 7: Failed to connect to localhost port 9666: Connection refused (see https:\/\/curl.haxx.se\/libcurl\/c\/libcurl-errors.html) for http:\/\/localhost:9666\/api\/spaces"

I also made sure my router has port 9666 open for my Pi’s ip address.

Any solution for this issue?
Thank you for any help

patcloud · January 23, 2022, 12:30pm

@mjeshurun, same problem here using NextCloudPi 22.2.3

tj0xin · February 12, 2022, 11:11am

Same problem with latest Nextcloud Hub, any solutions?

swindhab · February 13, 2022, 11:00am

Not working on Pi because of the binary not compiled for arm processors:

Same for you @patcloud and maybe you @tj0xin
