Accessing Flint 3 via Caddy

Routers
1

I use Caddy to my self-hosted services and computer. Thanks to that, I can use Caddy to convert 192.168.0.23 into tn.domain.com with a valid certificate. I only open ports 80 and 443. I only have to add this to my Caddyfile:

tn.domain.com {
reverse_proxy 192.168.0.23
}

I do this for a variety of services on my home network with no problems

I have a Flint 3 GL.iNet GL-BE9300

Locally to access the router I use 192.168.8.1 with no problems.

To access the router externally, I used the following in my Caddy file

gl.domain.com {
reverse_proxy 192.168.8.1
}

This brings up a blank page with the name of the page as “Admin Panel”. I tried to enter gl.domain.com in 3 different browsers with same results.

I can use Astro Wrap but the web address is harder to remember and it did not work when I was on a recent holiday away from my country. Also I prefer my use of Caddy for consistency.

Can anyone help?

Hi

It looks like Caddy may not be handling .js.gz files correctly.
Since we’re not Caddy experts, we might not be able to give detailed guidance on its configuration.

root@GL-BE9300:~# tail -f /var/log/nginx/error.log

As a workaround, you can decompress all gzip files on your Flint 3 by running the following command over SSH:

find /www/ -name "*.gz" -exec gunzip {} \;

(Please note: you may need to repeat this step after upgrading firmware, since upgrades can restore the original compressed files.)

Thanks for the advice.

Does the decompression of the files affect the operation of the router?

If this doesn't work can I undo the decompression by reinstalling the latest firmware?

Decompression of files does not affect the operation of the router.
It uses more storage space, and consumes slightly more data traffic (a few Mbytes) during access.

Yes, you can undo the decompression by reinstalling the latest firmware.

Thanks.

The command

find /www/ -name "*.gz" -exec gunzip {} \; worked.

I used the Windows CMD command

Thanks for this @will.qiu

Sadly, my post here was ignored for months but I’m glad the staff responded to someone else and that person sent me a message.

@harrisc Thanks for letting me know about this Chris. I really appreciate it.

I wish there was another way to fix this through the Caddyfile instead ofhaving to modify the routers files but I guess that’s all we can do for now.

Did you try contacting Caddy devs?
