188.8.131.52.1.1. Error "Failed to convert command to 8-bit encoding" in FileZilla
Cause of error "Failed to convert command to 8-bit encoding" ("Failed to convert command to 8 bit charset") is usually the use of national alphabets (for example, Cyrillic) or some special characters in the names of files and directories. The error can be observed after transferring files between devices on macOS and devices on Windows. To avoid such problems, it is recommended to use only the Latin alphabet and standard characters in the names of files and directories, which will be displayed in the same way in all encodings.
If you face this kind of problem, try turnon force UTF-8 for filenames and check for the problem.
Alternatively, you can try uploading the necessary files to the hosting with an archive and unpack it using the file manager. Then, if necessary, you can try transform file name encoding via the console.
