Afternoon, I've searched the forums for a solution to my problem and have had no success.
I'm unable to connect to my FTP server externally, If I'm inside the network everything works fine and I'm able to connect to the server and if I don't use any TLS/SSL (Externally) this also works, but as soon as I switch to Implicit I get the following error:
. 2019-12-06 15:04:53.013 Connecting to *IP Address* ...
. 2019-12-06 15:04:53.075 Connected with *IP Address*, negotiating TLS connection...
. 2019-12-06 15:04:53.122 TLS connect: error in SSLv2/v3 read server hello A
. 2019-12-06 15:04:53.122 Can't establish TLS connection
. 2019-12-06 15:04:53.122 Disconnected from server
I have setup a rule on the firewall to forward ports 20, 21, 22, 989, 990 (The control ports were previously open but I've shut those - clutching at straws)
I have tried passive and active modes (Makes no difference) as well as using Explicit TLS/SSL (This just times out)
Any help or ideas would be greatly appreciated!
