3.0.0: CGI program sent malformed or to big

Post by Atomic »

I've got a new Raspberry with Z-Way Server 3.0.0 and cannot access the fw updater.

All I get is this error message:

Code: Select all

Error 500: Internal Server Error
CGI program sent malformed or too big (>16384 bytes) HTTP headers: []
In the z-way-server log file I see no output when the error occurs.
I already started z-way-server manually as root using

Code: Select all

cd /opt/z-way-server/ && export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/z-way-server/libs && ./z-way-server --log-level 0
This may be related to https://forum.z-wave.me/viewtopic.php?f=3419&t=23701 but I'm not sure.

I tried to update according to https://z-wave.me/z-way-v3-0-0/ and after that I got the error: Error 500: Internal Server Error
CGI program sent malformed or too big (>16384 bytes) HTTP headers: [] when trying to update from my current version 2.3.8.

I updated from Jessie to Buster according to the instructions.
Did my update to Buster fail? Do I need to format my sdcard and do a clean install of buster and then install the latest z.wave.me?

Edit: Sorry, forget what I wrote above! I only updated to Buster according to the home page but I did not do the actual update to version 3.0.0.
I will try that tomorrow and see how it goes. I actually think the update to Buster failed though, there were some error messages along the way...

Please clean browser cache and cookies, update to v3.0.6 and again clean cache and cookies. Should help

Now I also did the “wget -q -O - https://storage.z-wave.me/RaspbianInstall | sudo bash” but no difference. Still cannot get past the error message “ Error 500: Internal Server Error CGI program sent malformed or too big (>16384 bytes) HTTP headers: [] “ when trying to update from my current version 2.3.8.
I cleaned browseer cache and cookies before and after the update attempt...

Tried to do a sudo apt update and received the no_pubkey E5958C31C0AFD761 problem that I saw in a different thread that people have had problems with.
Did not understand what to do though, because I am a total noob on Linux. I just follow and copy instructions to get the z-wave.me graphical interface to work. 😊

Did some repair to the installed packages and then tried to install again. Still got several error messages indicating that my sdcard was full, so I gave up and ordered a bigger sdcard to start all over on.
Started up my z-wave.me system and then suddenly it showed version nr 3.0.6! 😊
Don’t really know what I did that made it work, but I am not sure if it is a completely successful installation.
I directly noticed that my “if then” apps doesn’t work anymore.
Also, the whole reason why I wanted to upgrade from my perfectly stable 2.3.8 was that I have bought the new Qubino mini dimmer which should be compatible with z.wave.me in the latest sw-version. Unfortunately I cannot find that dimmer among the devices even in version 3.0.6... 😩

Good to know that now it is working.

The Qubino dimmer should work in Z-Way. What is wrong with it?
