+## Inspect Go runtime debug data
 
 If you started `rly` with the default `--debug-addr` argument,
 you can open `http://localhost:7597` in your browser to explore details from the Go runtime.
 
 If you need active assistance from the Relayer development team regarding an unresponsive Relayer instance,
 it will be helpful to provide the output from `http://localhost:7597/debug/pprof/goroutine?debug=2` at a minimum.

 The relayer looks back in time at historical transactions and needs to have an index of them.
 
 Specifically check `~/.<node_data_dir>/config/config.toml` has the following fields set:
 ```toml
 indexer = "kv"
 index_all_tags = true

 When preparing a transaction for relaying, the amount of gas that the transaction will consume is unknown.  To compute how much gas the transaction will need, the transaction is prepared with 0 gas and delivered as a `/cosmos.tx.v1beta1.Service/Simulate` query to the RPC endpoint.  Recently chains have been creating AnteHandlers in which 0 gas triggers an error case:

+<summary>invalid header: new header has a time from the future</summary>
+

+This is most likely an rpc issue. 
+The latest block time on the source and destination chain have likely drifted apart.
+
+You can confirm by this by checking the latest block time on each chain:
+
+```shell
+grpcurl -plaintext <GRP-URL:PORT> cosmos.base.tendermint.v1beta1.Service.GetLatestBlock | grep '"time":'
+```
+
+The solution here is to either use a different RPC endpoint OR if you are in control of the RPC, try restarting the node.
