Unable to install mwan3 package - (Failed to parse json data)

Software SW help

Hello, I am trying to set mwan3 on my Omnia.
I get stuck even on prerequisite - I am not able to ping anything, using second connection. After “ping -c 1 -I lan4 www.google.com”
I got message “ping: connect: Permission denied”.
This ping works, if the lan4 interface is set as “WAN” in Foris. But when WAN is set to wan port (eth2), than I got this permission denied message. I think it must be something with firewall?
The lan4 port has its own interface and the interface belongs to WAN firewall zone.
Does anyone have mwan3 up and running? Any idea what could cause this? Thank you.

Anyone please? Should I add some info?

Hi, I have an update, if anyone is watching. The problem here was an “-I” parameter. When I change it to lowercase “-i”, I am able to use that interface.
However, now I face another problem - I am unable to install mwan3 package. Even through LuCi, neither in CLI.

Mwan configure page in Luci is shown, but in CLI I am unable to restart the service (similar error message, so I think the installation is corrupted.
Can it be in my Omnia? Or should I contact Turris team because of corrupted package mwan3?

Hey @Victor_H were you ever able to figure this out? I am having the same exact issue. Failed to parse json data: unexpected end of data

Hi. I do not remember, however, mwan works now. I think I installed all updates and started from scratch.
