Hello there,
First of all: Thank DAppNode you so much for your efforts. This is a great project.
[Edit: github issue: https://github.com/dappnode/DAppNode/issues/187]
Now to my problems:
I am running DAppNode on my own NUC with geth and goerli-geth fully synced.
I succesfully establish my VPN connection over my LAN (via IP4), since for networking reasons (no public IPV4 address because of DS-LITE IP sharing, not willing to allow UPNP on my router and not willing of trying fancy IPV6 traffic rules at this point in time.)
When I connect my Linux Desktop via VPN, I can access the UI and everything seems to solve.
However, after a short while http requests to other sides slow massively down, and sometimes they are not reachable at all.
Also, after a while it the my.dappnode and other *.dappnode domains are not accessible anymore and I need to disconnect and reconnect VPN in order to get it working again.
Also, RPC request to the goerli-geth nodes (goerli-geth.dappnode:8545) work initially and then stop working after a while.
In addition, I am running lighthouse beacon and validators on another local VM (ubuntu server LTS 20.04).
There, I establish a VPN connection to my dappnode, and the behaviour is much more erratic even then on the desktop:
Initially, domains *.dappnode are resolved and pingable.
After a while, it stops working.
This can also be seen in the logs of the pyrmont lighthouse beacon:
Sometimes it works:
Nov 24 15:18:31 pyrmontt0 lighthouse[765]: Nov 24 15:18:31.417 INFO Imported deposit log(s) new: 1, total: 103300, latest_block: 3809046, service: eth1_rpc
and then some time later it doesn’t
Nov 24 15:19:08 pyrmontt0 lighthouse[765]: Nov 24 15:19:08.371 CRIT Error connecting to eth1 node. Please ensure that you have an eth1 http server running locally on http://localhost:8545 or pass an external endpoint using `--eth1-endpoint <SERVER-ADDRESS>`. Also ensure that `eth` and `net` apis are enabled on the eth1 http server, warning: BLOCK PROPOSALS WILL FAIL WITHOUT VALID ETH1 CONNECTION, service: eth1_rpc
Then again, it might work later again:
Nov 24 15:44:46 pyrmontt0 lighthouse[765]: Nov 24 15:44:46.407 INFO Imported deposit log(s) new: 1, total: 103310, latest_block: 3809150, service: eth1_rpc
And again not
Nov 24 15:45:55 pyrmontt0 lighthouse[765]: Nov 24 15:45:55.414 CRIT Error connecting to eth1 node. Please ensure that you have an eth1 http server running locally on http://localhost:8545 or pass an external endpoint using `--eth1-endpoint <SERVER-ADDRESS>`. Also ensure that `eth` and `net` apis are enabled on the eth1 http server, warning: BLOCK PROPOSALS WILL FAIL WITHOUT VALID ETH1 CONNECTION, service: eth1_rpc
The same is true for pinging/tracerouting/resolving .dappnode domains:
It works at times, then it doesn’t again.
Due to these connection problems I am losing attestations and will probably lose block proposals.
Any idea what is wrong?
