Client can connect and list directories in ftp server, but once starts to upload file, only 1mb is uploaded and then error 550 access is denied pops up. Client is using Filezilla. I tried from my office to coonect from inside and from 4G (outside) everything works. But client in other office tried 3 different PC's and the same error.
Here are logs from client:

Sound like quota related problem on that folder or user antzen. Did you try to upload something when loged as antzen and did you had same issue? You should test upload as admin to find out if you have user or folder quota problem. If quota's aren't problem, It could be firewall issue, so disable it and let your client test again and upload new log.
