2-3 weeks ago my website(serenityonlinetherapy.com) went down. My website host tech service fixed the problem by, they said, moving my website to another Windows server. Flash forward to today and for the first time since the change, I made changes to my website and tried to upload them (I use Expression Web) but got an Error message: “passive FTP mode not available,” which I have always used with success. So, I unchecked the button for using passive FTP and got a different Error message: “cannot connect with active FTP. Please try using passive FTP.” Next I was told by host tech support to use a different location ftp address instead of the one I had been using for years with success. That allowed me to see my login window, and so I put in my the same username and password I've always used, but it would not accept my password giving me, sometimes, a 530 error message. So, I went back to using my old FTP address. Next I was told by tech to change/reset the PW. I did that and it would not accept that PW either. Then I was told to download FileZilla and and see if I could make the FTP connection, and I eventually was able to. But I still can't make the FTP connection with Expression Web. The only thing I know that has changed is my website was moved to another server by my host. I have tried everything I can think of or have researched. I have turned off my Windows firewall and virus programs and I still get the same message - "passive FTP mode is not available." And my host tech support has not been able to solve the problem either. Any suggestions as to what might be the problem? Thanks in advance!
