Unable to find Zynthian for Webconfig [SOLVED]

Building Zynthian
21

Good morning to all and happy holidays if you are on vacation …

I have the same problem of accessing the web config because port 80 is NOT open.
With a network scanner I find the zinthian IP address but only port 22 is open where I can regularly access with WinSCP.
But I can not clearly make any web access if port 80 is closed, same thing with zynthian.local as the base is hijacked to the IP address. I performed various tests disconnecting the cable from the GPIO connector and leaving the raspberry 3 connected only to the power supply and to the network cable to the pc.

Some ideas?

Sorry if I have not written correctly, I’m using the google translator.

when you have ssh connection, you can "systemctl stop zynthian-webconf"
then
cd /zynthian/zynthian-webconf/
and finally
./zynthian_webconf.sh

Now you see log messages.

23

My guess is, that you didn’t update your system.

@jofemodo
where is the diagnosis script? :slight_smile:

24

Jeje! My guess is that @sevest is using an old SD image. All recent SD images have webconf running in port 80 by default :wink:

@mheidt, the disagnosis script is on the way. Give me some days …

Regards,

25

I confirm the error. I had downloaded the image of version 2 instead of version 1 …
Now it works properly, thanks.

26

Somehow it became impossible for me to enter the webconf. It just keeps loading (in safari) and in Firefox it gives me an error saying that it cant connect.
I can still connect via my ftp client and with terminal thou, so there must be some connection. I also tried updating, which changed nothing
Any ideas?

I dont know if the log helps anything, but here it is:

Access via ssh.

systemctl stop zynthian-webconf

cd /zynthian/zynthian-webconf

./zynthian-webconf.sh

Now you see error messages, if there are any.

28

ok thanks!
After doing what you said the terminal showed:

Summary

root@zynthian:/zynthian/zynthian-webconf# ./zynthian_webconf.sh
Traceback (most recent call last):
File “./zynthian_webconf.py”, line 46, in
from lib.upload_handler import UploadHandler
File “/zynthian/zynthian-webconf/lib/upload_handler.py”, line 32, in
import jsonpickle
ImportError: No module named 'jsonpickle’
root@zynthian:/zynthian/zynthian-webconf#

is this jsonpickle something to worry about?

when I open the webconf adress in the browser the terminal doesnt show me new stuff.

29

I would take a new image and start from scratch.
Or you play with update_zynthian, update_zynthian_data and maybe even update_system

You are not running the latest system.

30

ok strange i’ve run the update two times from the zynthian. How do I know if I’m on the latest version? Is is written somewhere what the most recent is? Do I always have to update many times to reach the new version?

How does this work, update_zynthian and the others? Tried typing it in terminal but it doesnt understand me ^^

31

You need to search it
I recommend starting from scratch,

32

ok I trief the terminal update options you mentioned. Unfortunately didnt help.
I’m going to download the installer and make a fresh sd. I wish I would have constructed my zynthian in a way that makes it easier to reach it ^^

33

Cut a hole. That’s what the original kit has and what I did with my self made cases as well.

34

I reinstalled everything now. And run the zynthian_update and zynthian_update_data.sh several times. When I boot I now get the red error message.
I’m also confused that the operation system still seems to be the same like before and you said its not the recent one, right? I updated with the zynthian_gorgona_next_rbpi3_pitft28-2017-11-14 file.

I could load the initial webconf screen though! But its password protected and ‘raspberry’ doesnt work?

In the log it looks very messy now:

Are you sure, that your soundcard is ok and configured correctly?

36

is there a way to configure the soundcard without the webconf?
I don’t know how to find out if its ok. Any hints? I have an audioinjector.
What I can say is that I could still use it normally except for the webconf, but as an instrument, before I put the new image on, so I guess the soundcard is surely not completely broken

37

show us the logs, when you start webconf manually. Pls search the forum how to do it

39

cool! Now, after manually opening webconf I could also access it in the browser. Then after beeing able to select my soundcard I’m back on the boat! Next step: rocket science!
