I recently installed Solid Explorer on a new phone, moved my SSH key over (2048-bit RSA) and it won't connect to my desktop, when the last phone I had (using the exact same key) could connect using Solid Explorer.

Has something changed in the supported algorithms? This is one of my favorite apps and I'd like for things to work correctly.

For the record, the key was generated using OpenSSH and the desktop in question is running Gentoo Linux. I am able to login using username and password, but that is less secure. No changes happened on the server side between the use of the two phones.

If there's any more info I can provide please let me know.
