GUI to CLI and receiving "Connection error. Check if wallet is running at 9256"

[holdenprkr]

Hey everyone, my GUI currently gets stuck at the loading screen so I decided to switch over to the CLI. Whenever I run 'chia wallet show' I get the error "Connection error. Check if wallet is running at 9256". Is there anything I need to do specifically to connect to my wallet after switching from the GUI to CLI? I'm on windows 10 and before I updated from 1.1.3, when I'd run 'chia start farmer' I'd get a traceback error from the wallet trying to start up but everything else seemed to start just fine. After updating to 1.1.4 I don't receive the traceback error, but I fear my wallet isn't actually connecting as I'm still receiving this error when running 'chia wallet show'

[araamouch]

I have the same issue, any help please?

[holdenprkr]

I just hopped on powershell today to try to run chia start farmer and received this Traceback on 1.1.4. I've pretty much decided I won't start farming until I'm sure I'm doing this right. Not worth the resources and time at the moment.

Any luck with anyone, same problem here. Just updated to newest version too 1.1.5

[Yamanipanuchi]

I am running into the same issue. Running Ubuntu Server 20.04, I look at the process's and it "Looks" like it running. I unfortunately cannot confirm it is running though.

[dolphyvn]

Im having same issue as well.

[blackjackfruit]

My terminal output when trying to start and stop chia. After doing chia stop all I also did kill -9 {PID} for the chia_daemon and then attempted to start chia.

My first question to the devs is, am I Farming and if so would I receive a coin with my plots?
Anything else I can do to further provide additional logging?

I decided to wipe my drive and reinstall Ubuntu 20.04 instead of dealing with uncertainty. No more "Connection error. Check if wallet is running at 9256".

[happy1989525]

Same issue here, dont't know how to fix it.

[alexey-sl]

Have the same issue.
Removing the file blockchain_wallet_v1_mainnet_******.sqlite
temporarily fixed the issue.
Wallet now working in cli

Who have this issue - just check when you start wallet
chia start wallet
It will throw a huge list of errors.
It seems the wallet DB is the clue

[guoqiao]

same issue +1.
Isn't that removing your wallet ?

[Buzzmovies]

I deleted the file and was able to use the GUI once again. I do have to resync the whole ledger but it's much faster since update #1.1.6.

[guoqiao]

I have verified, rm the .sqlite file and restart, worked for me:

mv blockchain_wallet_v1_mainnet_3045185180.sqlite blockchain_wallet_v1_mainnet_3045185180.sqlite.save
chia stop -d all && chia start farmer
chia wallet show

[adrianzhang]

I have verified, rm the .sqlite file and restart, worked for me:

mv blockchain_wallet_v1_mainnet_3045185180.sqlite blockchain_wallet_v1_mainnet_3045185180.sqlite.save
chia stop -d all && chia start farmer
chia wallet show

it works like a charming! Thank you dude.

[shegis-nn]

I have verified, rm the .sqlite file and restart, worked for me:

mv blockchain_wallet_v1_mainnet_3045185180.sqlite blockchain_wallet_v1_mainnet_3045185180.sqlite.save
chia stop -d all && chia start farmer
chia wallet show

it work for me also but now my wallet status shows 0 chia ... how to recover its status?

[guoqiao]

Hi @shegis-nn , sorry to hear that.
My wallet was empty, so I can do that.
For you, good news is, the first mv cmd just renamed the db file, it didn't actually remove it. So you can recover your database with:

mv blockchain_wallet_v1_mainnet_3045185180.sqlite.save blockchain_wallet_v1_mainnet_3045185180.sqlite
chia stop -d all && chia start farmer
chia wallet show

But this also means, you will go back to your orignial status, the db issue is not fixed for you.
You need to find other solution.

[Flint4]

Had the same error after unexpected power loss. Deleting the wallet database alone did not help. I found a chia_wallet process still running after stopping the full node. I killed that process, then started the farmer again. Worked.

chia stop -d all
ps -fC chia_wallet
kill -9 [PID]
chia start farmer

[PID] should be replaced the PID number shown by the ps command.

[Thorgrlm]

What is the ps command?

[KnowTheFuture]

I was having the same issue, and found the answer here.

Run the ps command, you'll end up with all of the processes that are related.

Kill each one according to the PID. I needed to do it for 8 separate processes, then "chia start farmer"

[jaredchu]

What is the ps command?

ps -ef | grep chia_daemon

[mattxlee]

After I start chia service: wallet, the problem is resolved.
run in command: chia start wallet before running any chia wallet commands.

If you are still experiencing the issues it is recommended to upgrade to the latest version of chia. Please download it from here: https://www.chia.net/downloads/

Since this issue has been open for a number of years without additional comments, we will be closing this ticket but if we have closed this ticket in error do not hesitate to reach out to us again with any followup questions, comments, or if the issue persists after an update.

Please note that upgrading major versions of chia generally requires the config.yaml to be recreated using these steps:
1. Stop chia
2. Rename the config or move it to a different directory
3. In CLI run chia init
4. Copy any custom settings from the old config to the new (plot drive directories, pool info, trusted node info, etc) - be careful here as yaml is very picky about formatting including those leading spaces
5. Start Chia

The best place to reach our support team is on Discord (https://discord.gg/chia) or by reopening this ticket.
