error when trying to downgrade 13.1.3 to 13.1.2

Good Morning

I wonder how to solve this problem! Not doing outdated versions 13.1.3 to 13.1.2!

Note the following screen where it shows the error. I need to do this procedure to change SM to another AP.

I tested with two CNUT versions, 4.8.1 and 4.9.18

thank you

Hi Ramon,

This error occurs when you have the Windows Firewall is turned on. Please check if the windows firewall is Turned On; turn it off and then Re-start the HTTP server from Update>>HTTP Configure and  then to upgrade.  Please let me know if you still face any issues.

Regards,

Hello
I did all the necessary steps, but still remains the same mistake.
I'm remote. But I'm in the same IP range!
Now I will try directly on site.

Thank you

I'm getting the same error when trying to upgrade a PMP 100 AP and it's SM.  It worked fine upgrading them to 12.1 but going to 13.4.1 gives the the error: 

Failed to upload file boot.image,java.net.SocketException: Software caused connection abort: socket write error

Did you come up with anything?  I tried to turn my firewall off and it still did not help.
