Problem with newly added subdomain is automatically redirect to SSL
I've already had a droplet which previously has been setup with:
- Nginx server
- A domain (example.com)
- Re-route www.example.com to example.com as always.
- Installed and config Let's Encrypt for both example.com and www.example.com
- All HTTP will be redirected to HTTPS.
So at current state, all will be redirected to https://example.com and it is working fine.
Now, I want to add a subdomain into this droplet. I visit Networking section, add a new A record
sub.example.com. 1800 IN A 188.8.131.52
The ping works fine, it can send the packets.
When I type the address sub.example.com to web browser, I mean plain
http://sub.example.com, it just automagically redirects to
https://sub.example.com while I haven't set up anything for SSL.
I also tried to add a virtual host entry for
sub.example.com to nginx server, it just keeps redirects to the same route
error_log to nginx server config. No entry added if I visit the sub-domain.
Anyone have idea on this case? I search over Internet but haven't found any case similar to mine.
