I have disabled the firewall on both the machines for now.
I have went every possible post around this issue but can’t get it to work. Please help.

Hi,

The servers are 100% synced?
VPS servers?

If the nodes are not 100% synced then add back the IOHK testnet servers inside the topology file, restart the node and after that :

  • on BP topology file add only the relay
  • on Relay run topology updater (where u will add the BP IP + port)

Cheers,

The servers are 100% synced? - NO
VPS servers? - YES

Where can I get the IOHK testnet servers details from?
Should I add them only to relay?
Topology updater - can you please share the relevant doc?

I am beyond impressed by your quick response. Thank you taking interest in my post.

Add only the IOhK testnet servers on both servers (servers will not connect to each other if are not synced)

https://hydra.iohk.io/job/Cardano/cardano-node/cardano-deployment/latest-finished/download/1/testnet-topology.json

Which guide did u followed?

I followed this guide

Added the IOHK testnet servers. Waiting for both the nodes to sync.
I think I completely missed the topology updater . Didn’t see it in the above document . Can you please point me to the write place from where I can install?

Ok,

Wait for the nodes to sync then configure:

On relay configure the topology file
On BP (after u set the relay) remove IOHK servers and add the relay IP + port

Use coincashew guide (testnet config)
