SFTP external storage access not working | RuntimeException: Invalid size

[4bob]

I think if you read my article and deal with it, you will be able to set up SFTP access again with Ubuntu 18.04 and OC 10.7 secure, without possibly exposing yourself to other problems during the downgrade from SSH2.php or other dirty hacks.

SFTP external storage access | RuntimeException: Invalid size

I found a note here: https://www.openssh.com/txt/release-8.2; ssh-rsa key (2048-bit) using weak hashing algorithm; Which pointed me to this: https://www.ssh-audit.com/hardening_guides.html I followed this guide to secure my ssh server, after that, there were no more problems. You should also move to modern Ciphers if ssh-rsa is the problem. Do you have console access?
