Bug description

Hi, I'm trying to "request free TLS certificates for your SFTPGo services using the ACME protocol and the HTTP-01 challenge type." But, running into the error below. I'm wondering if it's related to the fact that I'm using a domain name with emojis in it, that gets converted to punycode.

Error:

unable to obtain certificates: error: one or more domains had a problem: [XXXXX MY DOMAIN XXXXX] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: [XXXXX IP ADDRESS XXXXX]: Invalid response from http://[XXXXX MY DOMAIN XXXXX]/.well-known/acme-challenge/93SKvH2pyeC2o3nMPyeQ2MV7UNQktCMhnjPkmrqgRCg: 404

Steps to reproduce

1. Go to the web admin > configurations
2. Enter domain name with emojis in it
3. Click submit button.

Not a bug. I have it working now with an emoji domain.

Never tested emoji domains. Glad it works
