Hi Martin, do you have any suggestions on how to resolve. I tried disabling node-red to see if that worked but no success. Am open to suggestions on what to try.
If I have some extra time I will try a fresh SD card with the setup you verified for Stefan (specified vanilla neuron OS, install evok, and use the same evok.conf) to see if that will work.
@Martin-Kudláček said in After installation of a xG18 extention I get a Server Error 500 for the Rest Json:
Updated, Rebooted and same error:

My L403 just arrived yesterday and I’m trying to connect the xG18 and having the same issues with Stefan.
I was able to connect in node-red over modbus RTU directly.
However when I try to access through Evok (different SD card with the same base OS image: https://kb.unipi.technology/_media/files:software:os-images:neuron-node-red_image-20210426.2.zip), I get the exact same error message as Stefan.
