I recently renewed our SSL cert and ran into a problem with Wing FTP. The cert seems to work fine on our company web page, and after installing it on Wing FTP, it works fine for regular users. However, the admin interface at port 5466 became inaccessible after the update. The error returned is:
Secure Connection Failed
The connection to 192.168.0.12:5466 was interrupted while the page was loading.

Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://192.168.0.12:5466" rel="nofollow again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.
Note that everything worked fine before updating the cert.
I have filed a ticket with Wing FTP support and they havent' gotten me anywhere.
We are using it on linux. The version is from 2016, I'm not sure how to get a version number without being able to access the admin interface.
If I installed the latest version of Wing FTP, 1. is that likely to solve the problem, 2. Will that take out all our user accounts and passwords? We have a lot of them. I don't know if there's a way to back them up, especially without admin access.
What's the best thing to do here?
