Tvheadend

I'm using an Odroid C2 running Ubuntu

Linux odroid64 3.14.79-116 #1 SMP PREEMPT Tue Sep 26 01:19:06 BRT 2017 aarch64 aarch64 aarch64 GNU/Linux

tvheadend 4.2.4~xenial arm64 Tvheadend

It's not a permission problem. I can 'su - hts;cd /home/hts/recordings;touch 1 2 3;rm 1 2 3'

Will paste success and errors along with mount options. Will see if I can also attach some screenshots of web configurations.

Works (directory of recordings is /home/hts/recordings and it's local)

All recording fail and tvheadend basically stops. I did not change any configurations in tvheadend between these two tests. Just disabled my Autorecs rules and made the mount changes.

I have tried with both name and IP with the same result
