Can't fectch data from TestNet in SandBox

Sir · June 15, 2022, 12:39am

Hi all, please help to resolve the problem.

I started on WLS 2 (Windows Subsystem for Linux) and typed this command:
./sandbox up testnet

I get this:

Nothing happening there.

As I understand it can’t connect to TestNet as on section algod - goal node status i get last commited block 0.

What should I do in order to connect to TestNet and run my py scripts local?

Welcome to Algorand!

What OS and specs do you have?
You need at least 4GB of RAM and a fast enough SSD.

Can you check you are on the latest version of sandbox (git pull)?
Can you reset your sandbox (./sandbox clean, ./sandbox reset)?

That being said, getting stuck at 0% may rather indicate a connectivity problem.
Are you behind a proxy? Are you in a network filtering DNS queries?
Can you run dig -t SRV _algobootstrap._tcp.testnet.algorand.network +short and show the output?
As well as: (with the expected answer below)

$ curl -s http://oregong-algorand-test-1.algorand-testnet.network:4161/v1/testnet-v1.0/block/0 | base64
gqVibG9ja4qkZmVlc8QgB9rLS22e0UGxdXa9RZrmQh1IbaPU7yJHxAmjlrguoiGjZ2VurHRlc3RuZXQtdjEuMKJnaMQgSGO1GKSzyE7IEPItTxCByw9x8FmnrCDexi9/cOUJOiKlcHJvdG/ZTmh0dHBzOi8vZ2l0aHViLmNvbS9hbGdvcmFuZC9zcGVjL3RyZWUvYTI2ZWQ3OGVkOGY4MzRlMmI5Y2NiNmViN2QzZWU5ZjYyOWE2ZTYyMqRyYXRlzg7msoCmcndjYWxyzgAHoSCjcndkxCD//////////////////////////////////////////6RzZWVkxCBIY7UYpLPITsgQ8i1PEIHLD3HwWaesIN7GL39w5Qk6IqJ0c85c/uwXo3R4bsQgJ3hisbLS0SebtaGdDYdRj+cVAPEmuLozZ3W9NJoee3OkY2VydIA=

(if dig or curl are not installed, please install the relevant Ubuntu packages dnsutils and curl)

Can you also provide the file sandbox.log and the output of ./sandbox logs? (at least the last 20 lines)

Sir · June 15, 2022, 4:23am

Hello Fabrice,
Thank you for the answer!

I have 32GB RAM.

I tried to use ./sandbox clean , ./sandbox reset and it didn’t help as I agree, it looks a connection problem. I pulled repo today so I guess it should be the latest version?

I don’t have a proxy or DNS filtering (as of what I know).

Output of

command:

That looks good. Connection to DNS seems to work.
Let’s however check that there is nothing strange with dnssec and 8.8.8.8 (which is used by sandbox):

$ dig -t SRV _algobootstrap._tcp.testnet.algorand.network @8.8.8.8 +short +dnssec

Can you also try:

./sandbox logs and show the end
./sandbox status and show it fully
enter in algod sandbox ./sandbox enter algod and show the end of node.log

Thank you in advance for your assistance!

P.S. Since I’m new I had to replace https:// for REF in section #2 as I couldn’t save answer with more than 2 links.

fabrice · June 15, 2022, 4:07pm

It is very strange.

Can you upload the full node.log on github gists for example?

But maybe the best is to completely reset docker (removing everything there) and clone again the sandbox.

Sir · June 15, 2022, 4:24pm

I tried to do this yestreday, deleted everythin and then pulled again sandbox. I can do that again, but don’t think it would make any changes.

Here it is:

Hooe we can figure it out!

Sir · June 15, 2022, 4:26pm

I want to provide additional info.
I have the file config.testnet:

export ALGOD_CHANNEL=“stable”
export ALGOD_URL=“”
export ALGOD_BRANCH=“”
export ALGOD_SHA=“”
export NETWORK=“testnet”
export NETWORK_BOOTSTRAP_URL=“.algorand.network”
export NETWORK_GENESIS_FILE=“genesis/testnet/genesis.json”
export INDEXER_URL=“”
export INDEXER_BRANCH=“”
export INDEXER_SHA=“”
export INDEXER_DISABLED=“true”
export INDEXER_ENABLE_ALL_PARAMETERS=“false”

I added the last row as without it I would be getting this warn:

WARN[0000] The “INDEXER_ENABLE_ALL_PARAMETERS” variable is not set. Defaulting to a blank string.

But either way if I put false or true, it doesn’t change anything.

fabrice · June 15, 2022, 8:30pm

I see errors with DNSSec in the logs.
And now I see that the last dig command does not return a DNSSec sig.
It looks like your Internet provider or something on your network is blocking DNSSec.

Can you try to modify config.json inside ./sandbox enter algod to disable DNSSec:
that is add something like

  "DNSSecurityFlags": 0

in it.
