Surprises from FTP. Has anyone come across?

Question

FTP

Friends, what is it! The situation is as follows:
I moved under the wing of a new provider (I don’t know if this is important), at the same time I reinstalled the system and total comander, replacing wcx_ftp.ini from the old one (so as not to reload accounts). Further, the clinical picture: connects to my server (located in the ru-center) via ftp, downloads files, but! it is impossible to upload them back, the procedure hangs after transferring 8200 bytes. always the same number. (ftp-passive exchange mode). We put the active mode, and voila! download is on! however, if you try to upload a large number of files (more than 40) in the active mode, then again, the download is interrupted by the offline event. always at 13.34 MB.
I'm desperate! Can you help me sort out this mess?

Answer 1

Do you have space on the server? delete temporary files, junk mail, etc.
It is also possible that if pouring into several threads, then the server may break the connection, look in the settings for the number of threads. Also, try other clients.

Answer 2

most likely "anti-spam" features of your provider
