my lightning apps suddenly stopped working. I can login to my Umbrel, bitcoin node says it’s 100% synchronized but if I want to open any Lightning app, it won’t start. Lightning app gets stuck on opening. Ride-the-lightning app write an error “Error 500, Error: Connect Ehostunreach 10.21.21.9:8080”. Thunder hub says “Unable to connect to this node”.
I removed alias and color from lnd.conf that I changed two weeks ago but it didn’t help. Also restarting node didn’t help.
Any advise? Thanks.
