Had a brief (like a second) power outage last night. I can't get back into NR from Home Assistant because I'm getting a 502: Bad Gateway error. Tried restoring HA from yesterday, but that doesn't help.

Running HA and NR on an Odroid N2+.

I tried removing the folder "follow-redirects" and restarted NR, but I still get the 502, but with a different folder name in the error log.

This is the error log.

## patching file nodes/ui\_base.html Hunk #1 succeeded at 1162 (offset 631 lines). npm ERR! code ENOTEMPTY npm ERR! syscall rename npm ERR! path /config/node-red/node\_modules/follow-redirects npm ERR! dest /config/node-red/node\_modules/.follow-redirects-SJVnQEvE npm ERR! errno -39 npm ERR!

## Oops! Something went wrong. We are so sorry, but something went terribly wrong when starting or running this add-on. Be sure to check the log above, line by line, for hints.

Any help gratefully received because my house is currently dead.

That looks to me like a corrupted disk. Probably safest to restore from backup.
