Reftagger site seems to be down

For several days, there appeared to be sporadic outages. Now the whole server that serves the Bible texts is unresponsive.

The Tool tip doesn’t work.

Clicking on a text:
http://biblia.com/bible/nkjv/James%203.13-4.10

Yields this message:
504 Gateway Time-out

The server didn’t respond in time.

Left a message on company Facebook page, because I could find no other contact info.
