FTP connection issues

I really suspect a deep trouble with DW FTP client...

I have submit a bug a while ago, since one of the last Next and 2018 update...

A web project was accessible by DW (old build prior to 2017)... so I have exported the .ste file

4 different web project are layered on the same web server... different DNS, but same web master IP and same port

now with CC '2018 and next...

3 of them are accessible but the fourth...

I try filezilla, browser, cute, ultra... alll works but DW

I have submit a bug report... no answer until now

This is either something happening at the OS or router level.

You stated "I then could no longer access the website after the FTP failed". Does this mean you could BEFORE FTP?

If so, does this happen only with Dreamweaver FTP or does FileZilla cause the same behavior?

If you can get to southyubariverstatepark.org before an FTP attempt, try this BEFORE FTP. If not then do this anyway.

See if you can ping your site.

Open a Command Window and type: ping southyubariverstatepark.org

And hit [Enter]

I get 173.195.184.126 as the IP address. What do you see?

You can also try using telnet to check the port access.

First you would need to add the 'Telnet Client' feature from:

Control Panel\Programs\Programs and Features, Select 'Turn Windows features on or off', then check 'Telnet client', and click OK.

Then try to telnet to the FTP server with:

TELNET southyubariverstatepark.org 21

If it connects you should get a 220 Welcome message.

If you do then try logging into the server with:

USER [ftp_username]

PASS [ftp_password]

If this works you should get a 230 Logged on message.

[ftp_username] = The username you use in Dreamweaver, do not type the [] brackets.

[ftp_password] = The password, again, no [].

Have you tested using a dedicated FTP program like the free Filezilla Client?

It might be worthwhile, if you can upload there, at least your site will be updated while troubleshooting continues in DW.

If you can't upload from there, but can still access it from another network using the same devices (laptop or mobile), in addition to Ben's note, it could point to an issue with your local network hardware.

If all of your network settings are identical as far as firewalls and filters go, and your FTP credentials work from other physical locations, it could be a physical problem with your router. I had something similar happen years ago, where I could log in and upload without issue from anywhere but my home network. I could still get online and most other activities worked without problems, but uploading in DW and connecting to one online video game just wouldn't work no matter what settings I changed.

Turned out to be a known hardware issue with the router, replacing it fixed the problem instantly.

If you can access the server at a neighbors house but not your own, then I think we can safely rule out DW as the cause of the issue.  Next time you go into DW, click on Site->Advanced->FTP Log and try to log in via FTP again.  Let us know the error that is being returned in the log.

If you are able to use another computer not on your network, I'm thinking the issue could be server-side that is preventing your computer from accessing the server.  In that case someone on the other end will need to make sure your IP is whitelisted so that you have access if that is necessary, or remove you from a blocklist if you were accidently placed there.
