Hello, I try to connect my Umbrel node to Impervious Browser and I need a TLS Cert of my node, where can I get it in Umbrel?
Try: :~/umbrel/app-data/lightning/data/lnd you should have a tls.cert file in this directory
Thanks, no I have to figure out how to convert it to an Hex String, what I did is not working.
I found the answer somewhere else, here is how to get the hex string of the tls.cert:
xxd -p -c2000 ~/umbrel/app-data/lightning/data/lnd/tls.cert
I got the hex but Impervious doesn’t want to connect to my node. I tried troubleshooting it for a while and tried to do it local with no success. Each time Impervious starts locking me out after a few seconds after logging in and I have to delete all the config files to start over.
Have you (or anyone) been able to successfully connect their Umbrel node?
Same for me, impossible to make the lightning functions work, with my node or not. It’s really confusing. Let’s wait that it get improved
Ok, here is how I did it:
With the very newest Umbrel, find the cert in this folder:
Then use a online Pem-2-Hex converter to get your Hex. Copy entire contents of your .pem file for the conversion.
It should work at that point.
Same problem here. By looking into Impervious’ log, I get the following error message:
transport: authentication handshake failed: x509: certificate is valid for 127.0.0.1, ::1, 10.21.21.9, not xx.xxx.xxx.xxx
Sent that in the troubleshooting channel @ Impervious Discord server, and their answer was:
The SNI of a TLS cert is pinned to a specific IP. So you have to make sure that all lines up.
I don’t know what that means, unfortunately.
Since this thread has been marked as solved, I have opened a new one:
@Eluc I’ve found the solution for the connectivity issue, and now impervious is connected to my node. The solution is documented in that thread.
