ONTAP 9.5: unable to upload configuration via tftp to Linux tftpd

Does it work for anyone? Linux tftpd sends reply which is rejected by ONTAP with "port unreachable" which causes tftpd to error out.

cdot01 is node management interface.

Not entirely sure tftp is supported as outgoing. Have you tried using FTP/SFTP?

TFTP is listed in help output of "system confguration backup upload". And transfer also starts.
