Server disconnecting randomly, slow transfer rates, error codes

Hello Martin,
I am having weird issues with my ftp. Using a major reliable local hosting provider, never had problems before with dozens of websites with them. I already raised a ticket there too to investigate.

After connecting and initiating transfer, the server will gradually slow down in transfer speeds down to 0. Then it will disconnect. This happens immediately with first file transferred or after N files. It will also happen when connection is idle (despite keepalive or occasional uploads a minute apart).

Tried SFTP, FTP+SSL, the difference is mostly in error code despite same behavior. Sometimes there is error code 3 permission denied, which makes no sense at all :)

Session log attached.


thank you for any ideas,
Alexander

Did you try to connect from another site?
Did you try another client?
Do you have the same problem when connecting to other servers from your site?

Hello Martin,
yes, I tried other sites and computers with same result(thereby also other ftp client). Other servers worked fine.

I got response from hosting support staff explaining that this had been an issue with their loadbalancer and connecting using IP instead of hostname resolved the problem!

Thank you for looking into this.
