Have you read and understood the above guidelines?

Yes

📜 What is the name of the script you are using?

OpenWebUI

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/openwebui.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 12

📝 Provide a clear and concise description of the issue.

Script works perfectly with default settings. If using advanced settings, the container fails to get created and the script fails each when VLAN tag is added:

`curl: (22) The requested URL returned error: 400

[ERROR] in line 1123: exit code 0: while executing command bash -c "(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/create_lxc.sh)" ?
`

🔄 Steps to reproduce the issue.

  1. Run Script
  2. Choose Advanced Mode
  3. Assign VLAN tag
  4. Script fails

Paste the full error output (if available).

curl: (22) The requested URL returned error: 400

[ERROR] in line 1123: exit code 0: while executing command bash -c "(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/create_lxc.sh)" ?

🖼️ Additional context (optional).

Seems like VLAN tag is making it crash. I have 25 other VM/CT on this VLAN so network connectivity is fine.

And whats the Tag? No Info what you choose as advanced.

I use this every day and it Work fine. Single lxc is Not possible, because its Breaks before the LXC is created

I put it on a different VLAN. It didn't like the VLAN I wanted to assign it to; fine by me, I'll fix it with routing.
