Cannot sync files with foldersync lite and NCP

When I try synching files with foldersync on Android I get “Trust anchor for certification path not found”. If I enable “allow self signed certificate”, it fails without any particular error message. Maybe the self signed cert is still a problem?

Does anybody else have such issues? I’m using foldersync on another nextcloud instance with let’s encrypt cert without problems.

It didn’t want to do when selecting webdav as an account type. You can also select a nextcloud account type and this worked.
