FileZilla Forums

Hi guys,
we have problem with file upload with FileZilla.
We used the FTPs (implicit) with no changes for many months with no problems... Till yesterday we have randomly when uploading the error:

Error while transfering data: ECONNABORTED - Connection aborted

It uploads a few files and then it uploads a file with 0 byte size and the upload is stuck.

We have tried switch of antivirus, firewall, updated version -> 1.7.3,...
we tried to set up on plain FTP with same result.

Thanks for help...

Which client software (product and version) is at the other end of the connection?

we have tried FileZilla client 3.65.0

Something must have changed, software doesn't suddenly change behavior.

Do you by change experience higher than usual ping, or substantial packet loss?

Could the ISP at either end of the connection be blocking particular ports for some reason? Try configuring a different passive mode port range.

hello we have tried to change passive mode port range but with no success...
