Hello @JueBam and welcome to the Cloudron Forum.

1. you posted in the wrong category, I will move this post to the N8N category
2. are you really a Cloudron user? This is the Cloudron forum and not the N8N forum
3. I will edit your post to display the image correctly

yeah. I am a cloudron user.
Guess found the problem: increased memory limit in cloudron/n8n
