Appcrash with AUTH TLS and domain-name

staycomp · Post by **staycomp** » Thu Mar 05, 2015 9:53 am

CoreFTP LE v2.2 builds 1792 & 1835

Connecting using AUTH TLS, Windows SSL library, Allow Session Reuse:

When using an ip-address, connection is good.
When using a hostname (that resolves to that same ip-address), an APPCRASH event occurs.
Certificate on the ftp server is self-signed. Client asks to accept it.
Last message before crash is
LIST
Connect socket #1640 to xx.xx.xx.xx port xxxxx

unusual to see a crash in CRYPT32.DLL... This could indicate some other sort of compatibility or DLL update issue.

Haven't been able to replicate the issue yet so any additional information you can provide would be helpful.

Are you sure this crash is in the 1835 build also (log says 1792)..?

Is session reuse required for the server (uncheck it if it isn't)...?

Happens for multiple people from multiple locations on unknown platforms.

Happens in 1835 also:

See if the 1845 build fixes the issue (currently the "developer build" at the time of this post).
