I noticed the Bitcoin node on my Umbrel is very very slow at validating blocks. Its currently trying to validate blocks from three months ago.
I went to the log and below seems to be the only recurring error I could find
2024-07-25T00:47:39Z Socks5() connect to xxx.onion:8333 failed: host unreachable
I have searched online but I cannot find a fix to this error so my node can validate blocks at a normal rate
I am running umbrel 4GB memory (2.62GB is used and 1.36GB is left) and 1TB SSD (799GB is used and 185GB is left) and I have 21 apps installed.
Any advise on actions I can take to resolve this so my Bitcoin node can valid blocks at a normal rate?thanks
If you want to speed up the initial block download you can increase the cache size or only connect to clearnet nodes(Outgoing Connections to Clearnet Peers). You find both options under advanced settings in the webui of the bitcoin node.
I have deactivated “Outgoing Connections to Tor Peers” and increase the cache size to 1000MB
Also when I login, the Bitcoin node always showing starting with the data blank for a really long time even when the umbrel has been running for days. Is this normal or is there a fix for it? Thanks
I can see just one peer on the UI, and the block validation on the UI does not happen as often as on the logs. Is there a fix on the ui issue as the logs seem to be okay
My ISP does not allow me to forward a port. I used to have no UI issues in a previous umbrel version. Is there a way to fix the UI to match the logs without forwarding a port?
Also, can I use Cloudflare on multiple services on my Umbrel, for example, on btcpaysever and another app on Umbrel?
The error message you’re seeing, Socks5() connect to xxx.onion:8333 failed: host unreachable, indicates that your Bitcoin node is trying to connect to a .onion address using the Tor network, but it’s unable to reach it. Here are some steps you can take to resolve the issue and improve block validation speed:
1. Check Tor Configuration
Verify Tor Service: Ensure that the Tor service is running correctly on your Umbrel node. You can check the Tor logs for any errors.
Update Tor: Make sure you have the latest version of Tor, as updates can fix connectivity issues.
2. Network Connectivity
Firewall and NAT Settings: Ensure that your network allows outbound connections on port 8333. If you’re behind a firewall or NAT, configure it to allow these connections.
Check Network Latency: High network latency or intermittent connectivity issues can slow down block validation.
3. Node Configuration
Increase Peers: Configure your node to connect to more peers. This can be done in the Bitcoin configuration file (bitcoin.conf). You can add more peers to increase your node’s connectivity:
I have deactivated “Outgoing Connections to Tor Peers” and increased the cache size to 1000MB, but it still seems to validate the blocks slowly.
Please let me know how I can verify the Tor service and update Tor.
Also, how do I go about configuring my node to connect to more peers via Bitcoin.conf
I’m having the same issues, the bitcoin core node says its complete and HDD or SDD is at 450 MB, i have just installed mempool and the page is blank but it says “Backend is synchronizing (99%)” ??? I’m going for yet another restart. I’d actually like to move the blockchain data to an external 500GB SDD that I have USB3.0. But should fix this issue before moving there.
I have done the necessary Umbrel and Bitcoin code updates. I have been stuck on 94-95% since then. I don’t know what to do to resolve this. Please advise.
See my logs from today showing its still on 94%-95% range since then

CPU and RAM Usage- CPU is at 50% and RAM usage is 2.67GB out of 3.98GB
Disk Space- Its a 1TB Disk and there is enough space for the sync
Network speed is high
I have restarted the node multiple times. The device seems to be syncing but it is now at 93% as against 95% when I first posted about this. It syncs less blocks that the new blocks created each day
