My operating system is (include version): Windows 10 Pro
I activate ISS Manager and added an FTP server only
Can somebody advise me how to get an SSL Certificate for it…
Thx Rob72
Thank I will look in it… Thx Rob72
just so you have some context and i should have been nicer
A) lets encrypt uses a client to get certificates
B) if you are new and just want to dip your toes in the water i recommend zerossl (slightly manual but it works)
C) its worthwhile reviewing the challenge types and what you require to do for each one
review an article i wrote on this ( a little bit wordy) https://www.linkedin.com/pulse/lets-encrypt-part-1-issuing-installing-certificates-andrei-hawke
other people have different takes and different clients they use but the process is about the same
A) Obtain a certificate
B) convert to PFX
C) Import to trust store
D) apply certificate to service (FTPS in your case)
shout out if you get really stuck and I will post some screenshots
I work with IIS quite a lot so understand what you are trying to do 
Super, thanks a lot Rob72 Age one year later now 73
Hello ahaw021
I fix my certificate by using my existing certificate with a new CCR to “Comodo CA” final result in an new certificate at no cost.
When I connect FTP Plain text it is running fine, ( Is NOT secure)
When I connect FTPS (Secure) next error
227 Entering Passive Mode (192,168,2,1,244,140).
Server reports local IP -> Redirect to: xxx.xxx.xx.xxx (Remove my IP Address)
Cancel pressed!
PORT 192,168,2,1,244,142
501 Server cannot accept argument.
Port is redirected to original IP Address
Looks like ISS Can’t handle this port request…!?
I have only forward port 21-22 to 192.168.2.1 (My PC)
QST, do I have forwards a range of other ports?
Thx Rob
i don't understand this statement at all
as for the rest of your issues they are FTP related. This is not a forum for FTP troubleshooting 
So I suggest you post that problem on a more appropriate forum.

Yes agree I will find an others forum..
Thx for you reply, Rob72
