Help with Testnet relay error

I am new to creating stake pools and am a bit lost. Hope someone can assist me. I started building a test relay node on an Ubuntu Virtualbox yesterday and left it running overnight to build the db. This morning I discovered that my host OS (Windows) rebooted because of Microsft updates :frowning:

I started running the node again and I got all sort of errors (see snippet below):

It does not seem to be running properly as the slot number does not update when I run this command:
$ cardano-cli query tip --testnet-magic 1097911063
“blockNo”: 2287371,
“headerHash”: “aef965e0a82c1103e78454cfc6153996410126aa826176a3a16bb38d729d9f27”,
“slotNo”: 18023833

Tried reading through the forum and there was a suggestion to make sure Protocol is set to Cardano in the testnet-config.json. Mine is already set to Cardano so the problem may be something else.

Can someone be kind enough to give any suggestions please?

Update. I decided to try again so I deleted the db directory and ran the node again. It started again from the first epoch… but then a few long hours later, it again shows similar errors.

Can current Stake Pool Operators please share your experience if it really is this difficult to setup a node? Have you encountered similar errors? Excerpt of the part where it fails is below. Hope someone can help…

Realized I posted this in the Operate A Stake Pool section. Probably who no one is replying. Reposting it here in the Setup A Stake Pool Section.

Additional info. I did a check on the tip and I got the same slotNo when it hanged the first time.

$ cardano-cli query tip --testnet-magic 1097911063
“blockNo”: 2287371,
“headerHash”: “aef965e0a82c1103e78454cfc6153996410126aa826176a3a16bb38d729d9f27”,
“slotNo”: 18023833

Seems it is getting stuck at 18023833. Any way for me to clean up / delete the last transaction or epoch so I can proceed?

Hello. Any kind soul want to point me in the right direction please?

I ran into the same problem while following the stake pool course. Public testnet now requires Cardano Node 1.25.1. After updating I was able to continue the sync.

Hi I got the same error. So I will try update cardano. Do I need to set up everything or simply cardano-node ?

Just Cardano Node.

Thanks oneforall. I redid all the steps but used 1.25.1. Unfortunately, it stopped at the same slotno again (18023833). Do you have any other tip on what I may be doing wrong?

Hmm. What does “cardano-node --version” show?

I found the solution. Just start with a fresh cardano-node folder, checkout to 1.25.1 and build it. When you are building, don’t do anything else if you dont have enough ram memory could throw some errors and dont finish properly.

mkdir -p ~/src
cd ~/src
git clone
cd cardano-node
git fetch --all --tags
git checkout tags/1.25.1
cabal configure --with-compiler=ghc-8.10.2
echo "package cardano-crypto-praos" >>  cabal.project.local
echo "  flags: -external-libsodium-vrf" >>  cabal.project.local
cabal update
cabal build cardano-node cardano-cli
cp -p dist-newstyle/build/x86_64-linux/ghc-8.10.2/cardano-node-1.25.1/x/cardano-node/build/cardano-node/cardano-node ~/.local/bin/
cp -p dist-newstyle/build/x86_64-linux/ghc-8.10.2/cardano-cli-1.25.1/x/cardano-cli/build/cardano-cli/cardano-cli ~/.local/bin/
cardano-cli --version

You can reuse your last blockchain. Now it should continue extending new blocks.

Thanks. It didn’t work for me. Had reused my db. Will retry later maybe with a fresh install and new db

This was the fix for me, thank you @allfs. After updating the cardano-node from 1.24.2 to 1.25.1 the chain continued to be extended past 18023833.
