ISP has 'UPGRADED' hosting - FTP no longer works

[mcrossley]

I have seen several times, that FTP fails when it has managed to create a zero length file at some point. All further uploads to that file fail until you manually delete the zero length file on the server. I have no idea why this is!

Hi Mark
Have deleted the 0 byte files - next round of updates puts them back.
I have checked the file size at my end and it is as expected.

extract from ftp log for relevant set of uploads.
Still confused why there are // in the path.
Beginning to think my webhost just wont work with MX FTP

Response: 550 Can't check for file existence - what does this mean?

Btw: did you also try 'good old plain text' FTP?

[HansR]

And while you're at it: as binary is used, do you have utf-8 set to on?
If not, do so.

[mcrossley]

I think the 550 error is just saying the file does not exist, which is correct - it's just checking.

There are two FTPS compatibility settings you could try (FTPS can be tricky!). This will be trial and error though...

So the usual stop Cumulus, edit Cumulus.ini, restart Cumulus caveat.

1. Add the the following entry to the [FTP site] block...
DisableEPSV=1

See if that improves things.

If not then...

2. Reset the first entry...
DisableEPSV=0
add another entry...
DisableFtpsExplicit=1

See if that improves things.

If not then try enabling both of them!

If that doesn't work I'm coming to the end of my ideas.

Thanks for everyones suggestions, afer fiddling with various FTP settings and talking to my hosts, I now have a working system again.

[HansR]

Great.

But could you elaborate a bit so that we know too what the problem was? Thnx!

[Vegit8]

Great.

Yes; apologies
It transpired that I had been given wrong information by the support people.
as you suggested plain FTP worked, but SFTP doesnt - so I have gone back to them again asking how I can use SFTP
So not a total success

[HansR]

Thanks.

If the support has found the solution could you please communicate here.
And NOTE: you are using SFTP while according to the logfiles you tried FTPS. Those are two very different things! Both in settings as in execution. So be sure what you are asking and what you are aiming at.

[water01]

You might try asking them if SFTP requires a specific port to work. My ISP required I use port 3784 and once set it worked perfectly.

On the old hosting platform I was using SFTP/22
I was advised to use FTPS - which didnt work for MX
On your suggestion I used plain old FTP - which of course is unsatisfactory.

I am now pressing my host for an SFTP/22 solution

[HansR]

Ok. Thnx.

[Vegit8]

The saga continues
After discussions with the Hosting Co.
I can connect with SFTP / 22 using Filezilla, but when using the same credentials and settings in MX I cannot.

I suspect this is because I had to accept a new certificate from their server, I cannot see a way of doing this in the FTP config section of MX.

So i am still stuck using plain FTP... grrr

[mcrossley]

MX is configured to accept any certificate.

[Vegit8]

Hi Mark
Then I am at a loss as to why MX wont communicate.
It has worked perfectly up until now.

I'll have to consider changing host it would seem
