Trying to figure out why one of my switches in loaction x was able to download firmware upgrades no problem while the other gets the below errors. Both switches are brocade 6510 running 7.2.1d with same settings. Not sure what else to check. I did notice that the switch not able to downlaod the firmware also is not able to run supportsave from BNA either. This may be a another simpton of the issue, I don't know...
Any ideas would be appreciated, Thanks!
The server is inaccessible or firmware path is invalid. Please make sure the server name/IP address and the firmware path are valid, the protocol and authentication are supported. It is also possible that the RSA host key could have been changed and please contact the System Administrator for adding the correct host key.

Have you checked if all the concerned switches are connected at 100Mb/s Full duplex?
Do you see errors on Ethernet port of the switches?
Make sure no firewall is blocking the access to those ports also.

Here is what happened. Since I needed to get this upgraded to 7.4.1e from 7.2.1d. I used the CLI to upgrade to the interm version 7.3.1e first and during that upgrade I got this message:
INFO: Ciphersuite change on switch
HTTPS ciphers will be modified to be compatible with new firmware version
All packages have been downloaded successfully.
Firmware has been downloaded to the secondary partition of the switch.
After this install I went back to BNA and was able to run the second upgrade to 7.4.1e. It appears to me that the Cipher may have been the issue.
I am wondering if there is a way to determine if you have a bad Cipher from the switch itself?

did you use scp via BNA when upgrading from 7.2 to 7.3? Or ftp?

I remember some issues with SCP via BNA within certain code streams, the workaround was to use CLI for firmwaredownload instead, as you did. Future upgrade should be fine.
