Sadly, I haven’t been looking at your logs until now 
Log says: Mar 21, 2019 22:36:34.902 [0x7f3a9d791740] DEBUG - Detected primary interface: 30.30.5.38
It should have worked using 127.0.0.1 but seems like it doesn’t anymore
Please see Qnap faq.....read me first! Q22, and change your IP Address, as well as make sure, that it after that can reach internet and DNS.
Then run the bash script again
