Attempted Approaches

1. Basic Publishing

• Method: npx forta-agent publish
• Result: 502 Bad Gateway
• Registry: disco.forta.network

2. GitHub Container Registry

• Changed registry to ghcr.io
• Set up GitHub PAT
• Result: Same 502 error

3. Manual Docker Build/Push

• Built locally: ✅
• Tagged image: ✅
• Layer push status:

  d9059661ce70: Pushed
  93b3025fe103: Pushed
  4c3009faa752: Pushed
  56c050b536a6: Pushed
  1d634c7931e4: Pushed
  7bf47ff3592f: Pushed
  eee371b9ce3f: Pushed
  7264a8db6415: Pushed
  

• Final result: 502 on manifest push

4. Environment Cleanup attempts

• Cleared Docker cache
• Cleaned npm cache
• Removed all containers/images
• Result: No improvement

Current Configuration

{
  "jsonRpcUrl": "https://polygon-mainnet.g.alchemy.com/v2/MY-API-KEY",
  "network": "polygon",
  "dockerImageRegistry": "disco.forta.network",
  "agentRegistryAddr": "0x61447385B019187daa48e91c55c02AF1F1f3F863"
}

5. Authentication Variations

• Tried Docker login with different methods:
• Interactive login
• Password stdin
• Environment variables
• Result: Authentication succeeded but push still failed

6. Registry Configuration Changes

• Tried different registry configurations in forta.config.json
• Attempted both with and without explicit registry address
• Result: No improvement, same 502 error

Each approach resulted in the same 502 Bad Gateway error, suggesting a potential issue with the Forta registry itself rather than client-side configuration. Been trying along the whole day with no luck, I want to deploy the bot on Polygon network, using RPC by Alchemy
