SSH error unsuccesful negotiation of the key exchange

[paulravensky]

hello, after updating pterodaktyl I can't log in to sftp because it shows the message: SSH Error: unsuccessful negotiation of the key exchange algorithm

The reboot of the entire server has been done but the problem still persists. How to fix it?

I'm using the latest version 5

Are you using the same version of openssl dll file for both? If not, try to update FlashFXP's dll with newer version

I don't understand openssl? What should I do then?

I have downloaded dlls from https://www.dll-files.com
and replace with those downloaded. And the same result.

Try to copy openssl dll from filezilla to flashfxp's dir. It might work or it might not. I haven't used FlashFXP in a while with ssh to remember how exactly to fix it.
Or it's possible that FlashFXP needs to be updated to support these new protocols... which is obviously not going to happen for a long time.

Try my guide here: https://www.flashfxp.com/forum/flash...4-0-build.html

If It doesn’t work, I’ll post a new topic on How to update FlashFXP to OpenSSL 1.1.1x version.

Yes please, an updated guide for OpenSSL 1.1.1x would be awesome. I have tried to use the new dlls like in your mentioned guide, but they dont seem to load properly. The remote broser console only writes Winsock 2.2 and when trying to connect or transfer with SSL/TLS, FlashFXP just crashes.

Thanks in advance!
