"Timed Out Fetching CID 'QmaPE7..................'" During Sync/Block Processing on Private DID ION Nodes #335
Description
Subject: Issue: "Timed Out Fetching CID" During Sync/Block Processing on Private DID ION Nodes
Description:
I have deployed two DID ION mainnet nodes on different servers, both inside a private network. While I can successfully create and publish DIDs on these nodes, the nodes are unable to resolve any external DIDs.
Whenever I attempt to resolve external DIDs in any of those nodes, I consistently receive the following message:
DID not found
Upon reviewing the logs, I consistently encounter the following error during sync/block processing in ion-core:

Steps Taken:
- Verified the node configurations and ensured they point to the mainnet.
- Successfully created and published DIDs from these private nodes.
- Tested internal resolution of the DIDs created within these nodes, which works as expected.
- External DIDs always return "DID not found."
Additional Information:
- Both nodes are in a private network but have internet access for syncing.
- The CID fetching issue appears to block the ability to sync with the rest of the ION network.
Questions:
- What could be causing the "Timed out fetching CID" error during block processing?
- Are there specific configurations or network settings required to enable smooth synchronization with the public ION network?
- Could this issue be related to private network restrictions on IPFS or other underlying services used by ION nodes?
Environment:
- DID ION Node version: custom build based on sidetree repository.
- Operating system: Ubuntu 20.04
- Deployment: Docker-based
I would appreciate insights from the community, particularly from @csuwildcat , @thehenrytsai and @transmute-industries, as their expertise on similar issues would be invaluable.
Thank you in advance for your support.
