530 Login incorrect on cloud webspace

Hi,

webspace on servage.net is in a cloud.
Sometimes it happens that I cannot reconnect with FlashFXP (it occured 2 times now).
If I start another instance of FlashFXP everything works fine.
After a short while I'm able to reconnect successfully with the old instance.

I detected that the domain ftp.servage.net returns different IP addresses.
I don't know whether it's a bug in FlashFXP or it's a misconfigured server cloud.

The used protocol is FTP on port 21. No encryption is activated.

[IP1], [IP2] and [IP3] are different IP addresses.

First FlashFXP instance:

More and more I think their servers are misconfigured.
I started a new FlashFXP instance automatically connecting to their servers and directly got an 530.

Yes, this is problem with your hosting provider.
Contact them and tell them that when you connect to some IPs it works, but that specific IP can't log you in.

This is not FlashFXP's fault.
