Hi, I’m having a hard time with my node. I rebooted it yesterday after seeing that my node lost its IPv4 connectivity. Since then, the node has been having a hard time to connect to peers. I ended up adding manually nodes through the following command: > ./scripts/app compose bitcoin exec bitcoind bitcoin-cli addnode After adding many nodes i manage to have around 15-18 peers ( clearnet & tor ). However the node does not download the missing blocks and therefore does not sync. The bitcoind logs show some recurring elements that tickles me but i might not understand fully. The first one is this : > 2023-02-09T14:19:52Z Potential stale tip detected, will try using extra outbound peer (last tip update: 3778 seconds ago) The second one is this : > 2023-02-09T13:58:36Z Timeout downloading headers from peer=61, disconnecting I don’t get why this happens nor what i can do to resync the node. I must admit i’m a bit stressed out as i have 7 channels opened on LN that i can not manage nor monitor until the node get resynced. Any help would be really appreciated \<3 P.S : I ran the following command, no inconsistency found : > ./scripts/app compose bitcoin exec bitcoind bitcoin-cli verifychain 4 100 EDIT : A bit of information regarding my node : Umbrel Version: 0.5.3-build-d6641f8 Bitcoin & LND app versions are up-to-date. Feel free to mention if there is any information missing here that could be useful ---

Can you verify that node is getting out to the internet? If you can ssh in just use ```auto ping 8.8.8.8 ``` If that works make sure your dns is working with ```auto Ping google.com ``` You can also SSH and run this command to get your logs ```auto sudo ~/umbrel/scripts/debug ``` There is instructions for how to ssh in the faq [FAQ](http://community.umbrel.com/t/official-umbrel-troubleshooting-guide-and-faq/9873) ---

Hi @ParkerS, sorry for answering that late. Yes, the node had access to the internet. Everything looked to run fine. I ended reindexing the chainstate, which seems to have fixed the problem. It took a few days due to latency of the connection but after reindexing the local bitcoind managed to catch up with remote peers. I still have no explanation on what happened. I uninstalled many applications to see if any could be source of the problem, nothing was changing. Digging on the web i found this: [https://bitcoin.stackexchange.com/a/115298](https://bitcoin.stackexchange.com/a/115298) . However i found it after starting the reindex and didn’t think on trying to uninstall mempool first, so i can’t ensure this could be linked. ---

hey @ParkerS, I was having a similar issue, since October 2023, and I reflashed my SD (on the current and a new one) and am able to get into the Umbrel home, but now I cannot connect to any app - Bitcoin never updates/loads/refreshes, stuck in “Starting”, and Mempool says OFFLINE with flashes of RECONNECTING… so seems like it’s not online. I followed the SSH instructions and logged into my node that way, and tried pinging 8.8.8.8 - didn’t seem to work… just kept pinging for a long time (vs. when I do it from my local computer, it worked after 4 pings no problem). How do I troubleshoot getting my node back on the internet? It’s clearly connected to my router because I can SSH in through my wifi. Troubleshooting log is attached (from after my Umbrel OS update to 0.5.4 Thanks in advance!
