Panic error

[tluyet (travis Luyet)]

our server unexpectedly shutdown and when it came back online syncthing didn’t come back up.

When I run it manually I get this error: panic: runtime error: index out of range [1] with length 1

I don’t really know where to start. should I reinstall syncthing? Should I delete the syncthing databases? If so what do those files look like? extension? location?

Thanks

This is a bug in rc.4. You have to upgrade manually (either run with syncthing -upgrade or replace the binary with a newer release): See Immediate crash on start (1.15.0-rc.4) · Issue #7486 · syncthing/syncthing · GitHub
