I am constantly getting below error -

```auto
rpc error: code = Unknown desc = While proposing error: context deadline exceeded

```

I googled and could not find any helpful resource.

Is your Dgraph Server up and running?

I have aerospike and dgraph both running and I insert data on both of them.

As soon as I have inserted data to aerospike, I put the data in dgraph. And the UID generated by dgraph is put back to aerospike bin.

The error comes right after using below code -

```auto
assigned, err := dg.NewTxn().Mutate(ctx, mu)
// Here error comes
rpc error: code = Unknown desc = While processing error: context deadline exceeded

```

I use `assigned.Uids["blank-0"]` to put inside in aerospike bin. I get

I use aerospike and dgraph because - First is extremely fast in reading and fetching data and later is extremely fast in writing data, So, I have plan to build connector for both of them for my use case.

Is this with one Zero and one Server? Do you have connection logs when Dgraph started running and can share the commands you used to run Dgraph?

Yes, it is with one Zero and one Server. Now, I can see all of a sudden my all write to dgraph is throwing an error - “context deadline exceeded”.

It was not the case earlier.

Just to provide more detail, below are some of my code work -

```auto
conn, errGraph := grpc.Dial("127.0.0.1:9080", grpc.WithInsecure())
	if errGraph != nil {
		panic("Error! While trying to dial gRPC!")
	}
	defer conn.Close()

```

and usual write operation.

Thanks. Is the firewall issue from earlier resolved? The commands used to run Dgraph Zero and Dgraph Server are ok.

Yes, I have put back my firewall state to original state. Same state where I had successfully inserted the data, but no luck, error is still there.

While writing this post. I tried running the code again by turning off the firewall completely but the error is still there.

I am sure, it’s not firewall now. I am seeing the error after below incidents.

* * *

Earlier, I was running my golang app on URL “[https://localhost:1443](https://localhost:1443)” and just to check on mobile, I switched my app to run on URL and address “[https://192.168.0.2:1443](https://192.168.0.2:1443)” and after checking, I switched back to “[https://localhost:1443](https://localhost:1443)” and since then I am getting this error.

Can you share the output with `dgraph zero` and `dgraph server` again? Including the version information from the beginning.

Did you go through the [Upgrade Database procedure](https://docs.dgraph.io/deploy/#upgrade-database) with your existing data?

No, as it’s development server, data is not important - so I can delete all and start fresh. That is not a problem - Is dgraph server not restarting error due to old data?

**UPDATE** : I deleted the old data and ran again, it’s working now.

I will start checing insert of data again to see, if I still get error

Possibly. As per the [upgrade database docs](https://docs.dgraph.io/deploy/#upgrade-database):

> Dgraph’s underlying data format could have changed, and reloading the export avoids encoding incompatibilities

I updated the dgraph to `1.0.7` and started with fresh data. The error is gone now. Application is working fine.

I could not find much detail on why this error occurred in first case though,

Thanks a lot @dmai - for helping me through out until here.
