nfs share fails to mount on boot but mount -a works fine

[charliepapa]

All the symptoms point to a problem with timing - like the network is not ready or something. I have tried all the suggestions for delaying the mount that I can find. Currently the fstab line is :
192.168.15.71:/mnt/manapool/media /mnt/banx/media nfs _netdev,soft,timeo=30,retry=5,rsize=8192,wsize=8192,tcp,intr 0 0

I would like to use fstab if possible. I tried some other solutions like a reboot cron job to run mount -a but that failed so I retreated from that rabbit hole to focus on trying to get fstab working because if I do something unconventional it will come back to bite me in the fuure. Any suggestions would be appreciated - or if there is a best practice solution I am happy to learn it.
The nfs server is TrueNAS - all permissions must be good since mount -a works.

Have you looked into the system log at the time of the error? Often there is some error about it documented.

soft,rsize=8192,wsize=8192

These options are really bad and should NOT defined at all, use instead
192.168.15.71:/mnt/manapool/media /mnt/banx/media nfs defaults,_netdev 0 0
