Problems with new server build and v1 to v2

Help
#1

1. Caddy version (caddy version):

v2.3.0

2. How I run Caddy:

batch file

a. System environment:

Windows 10

b. Command:

caddy run

c. Service/unit/compose file:

d. My complete Caddyfile or JSON config:

connormorse.com 

reverse_proxy /ombi/* 192.168.0.1:5000
reverse_proxy /sonarr/* 192.168.0.2:8989

3. The problem I’m having:

Built new server and copied v1 caddyfile across but am running into issues where it is stuck on trying to solve http-01 challenge when changing to v2. v1 doesn’t work either.

4. Error messages and/or full log output:

5. What I already tried:

Tried v1 which used to work but fails on rate limit, I have waited a week but still the same issue, maybe I didn’t wait a full week and tripped the limit again? Sorry for lack of information I am not well versed in this stuff. I would appreciate any help :slight_smile:

6. Links to relevant resources:

#2

Are you sure Caddy is publicly accessible on ports 80 and 443? Are your ports forwarded correctly? Is Windows’ firewall preventing connections from reaching Caddy?

#3

I’ve port forwarded on the router and opened up both TCP and UDP on the firewall for both 80 and 443.

#4

This also appeared in the log which didn’t appear before, maybe this offers more insight?

#5

Yeah - that means something between Let’s Encrypt and your server is intercepting the request. Are you using something like Cloudflare, or some other CDN?

#6

As you mention Cloudflare I was reading another one of your replies on a similar thread, turned the clouds to grey so it’s DNS only and its working! Apologies for being so daft, does this setup still give me similar protection to what the CDN offers anyways?

#7

No, a CDN like Cloudflare will help protect you against DDoS attacks and make your site load faster to a global audience. However, many people argue that not using a CDN in between is more secure because the TLS certificate presented to the client is the same one as issued by the origin server, i.e. no middleman decrypting the connection and then (maybe) re-encrypting it to your site.

You can still get a TLS certificate behind a CDN or other proxy with the ACME DNS challenge.
