Import .xlsx and .csv

I am able to import .dtable file but when I tried to import .xlsx and .csv I am getting error as “Internal Server Error”. My system IP is “192.168.0.1”.

And here is the content of my host file
127.0.0.1 localhost
127.0.1.1 server-System-Product-Name
127.0.0.1 example.seatable.com
127.0.0.1 storage-server

I have checked the error under the inspect > console > Network

screen shot attached…500 error.

I have configured Seatable developer version. Need Help asap
