GUIDE: How to fix "Error: Received a non-OK status code"

[r2fo]

"Error: Received a non-OK status code" means that your instance is blocked by StackOverflow, to 'fix' this you can route the traffic of the AnonymousOverflow container over a VPN using GlueTun.

I couldn't find any straightforward guide so I wrote this one after a little bit of research, I opted for Cloudflare Warp since it's free and traffic is encrypted with HTTPS anyway. But you can use any of these providers, in that case you can skip to step 7 after adding your AnonymousOverflow ports to GlueTun's docker compose file.

1. Install wgcf
   https://github.com/ViRb3/wgcf/blob/master/README.md (this tool generates a WireGuard config for Cloudflare WARP)

2. Run wgcf register and accept the terms and conditions of Cloudflare

3. Run wgcf generate to generate a WireGuard config (this will save to wgcf-profile.conf)

Now we're gonna install GlueTun, it's a VPN client in the form of a Docker container. We need this to actually use the WireGuard config we generated

4. First create a folder for GlueTun
   mkdir gluetun

5. Inside of that folder, create a docker compose file using nano docker-compose.yml and paste the following:

version: "3"
services:
  gluetun:
    image: qmcgaw/gluetun
    cap_add:
      - NET_ADMIN
    environment:
      - VPN_SERVICE_PROVIDER=custom
      - VPN_TYPE=wireguard
      - VPN_ENDPOINT_IP=
      - VPN_ENDPOINT_PORT=
      - WIREGUARD_PUBLIC_KEY=
      - WIREGUARD_PRIVATE_KEY=
      - WIREGUARD_ADDRESSES=
    ports:
      - '80:8080' #edit these

Modify the ports values to those that you use for AnonymousOverflow

Copy the values for VPN_ENDPOINT_PORT, WIREGUARD_PUBLIC_KEY, WIREGUARD_PRIVATE_KEY from the wgcf-profile.conf that we generated using wgcf generate

For VPN_ENDPOINT_IP, you need to ping engage.cloudflareclient.com and use that IP address, for me it was 162.159.192.1

For WIREGUARD_ADDRESSES, you only need to copy paste the IPv4 address (not the IPv6). For me it was 172.16.0.2/32

7. Now run docker compose up -d to start the GlueTun container and take note of the container name
8. Now edit the docker compose file of AnonymousOverflow and add the following line at the bottom so that all traffic gets send through the GlueTun container. Modify it with your GlueTun container's name and remove the parentheses

    network_mode: container:(name of the GlueTun container)

Remove the ports from AnonymousOverflow docker compose file, since we already added them to GlueTun's. The reason we did this is because Docker doesn't support setting a network_mode and publishing ports at the same time

And then finally run docker compose up -d to start AnonymousOverflow with the new settings
