I’m trying to sync a grin node on floonet and it keeps getting hung up on step 1/4 downloading headers. ![Screenshot_2019-01-08_04-16-11](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/1X/36db8686105dcc27b04b24a8234389c7ce222424.png) When I run the log, I see the following series: 20190107 17:33:16.260 DEBUG grin\_chain::chain - body\_sync: body\_head - edc758c1, 0, header\_head - 0104492c, 14592, sync\_head - 0104492c, 14592 20190107 17:33:16.451 DEBUG grin\_chain::chain - body\_sync: need a state sync for txhashset. oldest block which is not on local chain: 026ea624 at 1 20190107 17:33:16.451 DEBUG grin\_servers:😁:sync::body\_sync - body\_sync: cannot sync full blocks earlier than horizon. will request txhashset 20190107 17:33:16.461 DEBUG grin\_servers:😁:sync::body\_sync - body\_sync: no pending block request, asking more Can anyone help me diagnose this problem?

This should now start downloading the whole chain state as one big file. Any other occurrence of the word txhashset in your logs? Do you have a slow connection? Status should update once in a while telling you about said download. ---

So I have the node running now, but the chain height is stuck at 0. When I start the server, I have about 10 peers, but all connections are outbound. The number slowly ticks down to one or two (both of which have a chain height of 0). Is there any reason why I might not be able to connect to peers. I’ve already followed the steps here except I haven’t removed peers directory yet (which I found in chain-data…not sure if that is the one): > [@Debugging sync issues](https://forum.grin.mw/t/debugging-sync-issues/145): > > You’re either starting a brand new Grin testnet node, or have been running it for some time but it doesn’t seem to be updating with latest blocks anymore. First, make sure you’re running a recent version of the code. If your build is more than a couple weeks old, update and retry. If you’re up-to-date, check the head of your local chain: curl localhost:13413/v1/chain Compare the resulting height and hash with: [Grin Explorer](https://grinexplorer.net/)[Grin Scan](https://grinscan.net/) If you’re really late on the chain and not updating, her… Here are the relevant screenshots: ![Screenshot_2019-01-08_12-16-26](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/1X/98e841e3da4b99767e0daeb45b910ac2bdcaa49d.png) ![Screenshot_2019-01-08_12-16-42](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/1X/3bf54ba459f912169557eb7f0c80eaf10046a2f9.png) UPDATE: added hard-coded peers according to the post [here](https://forum.grin.mw/t/issue-syncing-grin-node-0-4-2/1588/9). Still running into the same issue. ---

Hello, Like many, I want also to install a node. What’s the recommended version to install now ? is it fine with v0.5.1 , or too risky ? It will be on Debian 9.6 64bits 16GB. PS: Thanks to the devs for all the great work. ---

It looks like I keep losing the connection with the other nodes as I’m syncing. Looking through the logs, I keep having the following error: 20190108 13:15:52.229 DEBUG grin\_p2p::peer - Client 35.246.154.78:13414 connection lost: Connection(Custom { kind: ConnectionAborted, error: StringError(“read\_exact”) }) ---

I installed grin v0.5.1 on a Debian 9.6 16GB. Install seems successfull, and grin --help, grin server help, grin wallet help, returns what expected But when I run > grin --floonet just nothing happens There is even no grin process running ? What I’m missing ? ---

Did you adjust any of the settings in the .toml file? ---

Thanks for the advice. No I didn’t touch any of those .toml settings (but I’ll have a look).
