Jörmungand testnet: "Error fetching the genesis block from the network"

Staking & Delegation Operate a Stake Pool
1

I’m trying to setup a staking pool but quite frankly I get one problem after the other.

I previously installed a node on a server following this tutorial:
https://guides.poapool.com/create-your-own-cardano-stakepool/setting-up-the-node

The node seemed to work fine and sync at the beginning for a few weeks. Then I had problems with bugs on deadelus to get my tADAs (see other post), so I lost time.

Now daedelus works in version 2.2, I come back to my node on my server and I see that it has stopped syncing since 16 february, while repporting to be “running”. I decide to start from a frech chain, and delete the old chain. And I now get:

I’ve seen new versions of Jörmungandr have been released. I’ve tried few of them including 0.8.9 mentioned in the tutorial, and the latest 0.8.13, and 0.8.6 which seems to be recommanded here https://hydra.iohk.io/build/1579767/download/1/index.html. With no difference. Also should we update the node every-time a new version is released? (And if so how can we do it without service interruption?)

Thank’s in advance.

Ps: my internet connection does not show any sign of weakness.

Very strange it works again, just by starting the same program. I did it many times few hours ago, and it did not work. why?

I’m currently running 0.8.6 which version should I run preferably?

As with most software, unless there’s some specific reason not to (such as compatibility with other s/w), you should always run the latest version.
