Support and Troubleshooting

Brand new Umbrel Home. Installed bitcoin Synced and running. Installed LND. Was running. I restarted Umbrel, and LND now errors out and won’t start.

Logs are full of this error.

lightning_app_1 | E0610 00:54:50.785564211 31 ssl_transport_security.cc:1245] Handshake failed with fatal error SSL_ERROR_SSL: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed.

Here is the log file.

I fixed it by deleting the tls.cert and tls.key.

I have the same error, how did you deleted the tls.cert and tls.key.? Thank you

You’ll find those files in ~/umbrel/app-data/lightning/data/lnd

Just delete the tls.cert and tls.key files you find there and then restart lnd.

5

Sorry for the ignorance. But how can I reach that folder? thank you

6

SSH into your Umbrel.

rm ~/umbrel/app-data/lightning/data/lnd/tls.crt

rm ~/umbrel/app-data/lightning/data/lnd/tls.key

Then restart lnd.
