File Manager: Unknown Error: HestiaCP 1.6.2, Ubuntu 20.04

Hello,

I am facing Unknown Error in File Manager of HestiaCP 1.6.2, and I am using Ubuntu 20.04LTS.

I have done the fresh installation three times, but the error is still there.

I have almost tried each and every method given on the forums, like removing .ssh folder contents, being able to login to SFTP using the admin account, tried to reset the password, also checked the sshd_config file, and compared it with other installations which do work fine.

But I am not able to fix this UNKNOWN error issue on File Manager of fresh installation of HestiaCP 1.6.2

Please help!

File Manager shows unknown error.

I have tried each and everything given on your forums. (forum.hestiacp(dot)com/t/file-manager-unknown-error-error-500/1221/48)

But I am not able to fix it.
