What is being checked

info: KOGR-LP - Minneapolis, KS
From the NRSC list: 98.50 MHz, PI code 35A5, FCC facility 780037.
info: RadioDNS lookup name
09850.35a5.3a0.fm.radiodns.org (frequency 98.50 MHz, PI 35A5, country code 3a0)

1. RadioDNS registration

pass: Registered
09850.35a5.3a0.fm.radiodns.org points to the station's authoritative domain: oakgroveradio.com

2. Service discovery (SRV records)

pass: _radiospi._tcp.oakgroveradio.com published
priority 10, weight 0, port 80 -> oakgroveradio.com
pass: _radioepg._tcp.oakgroveradio.com published
priority 10, weight 0, port 80 -> oakgroveradio.com
info: _radiovis._tcp: not published
Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.

3. Service Information file (SI.xml)

fail: HTTPS endpoint https://oakgroveradio.com:80/radiodns/spi/3.1/SI.xml is not reachable
TLS/certificate problem: OpenSSL/3.0.13: error:0A00010B:SSL routines::wrong version number
What to do: Check that the server is running, the port is open to the internet, and the DNS name is correct.
pass: HTTP endpoint http://oakgroveradio.com/radiodns/spi/3.1/SI.xml answered
71 ms, 4,197 bytes
warn: The SI file is served through a redirect
http://oakgroveradio.com/radiodns/spi/3.1/SI.xml -> https://oakgroveradio.com/radiodns/spi/3.1/SI.xml
What to do: Some receivers do not follow redirects. Serve the file directly at this address if you can.
pass: Content type is text/xml
Accepted. (RadioDNS's own guide shows application/xml.)
warn: SI file has no caching headers
What to do: Add Cache-Control: max-age (for example 86400 for 24 hours). Without it, receivers guess - and some ignore the content.
warn: The file does not strictly follow the official SI schema (3.1)
line 91: Element 'radiodns', attribute 'serviceIdentifier': [facet 'pattern'] The value '780037-1' is not accepted by the pattern '[a-z0-9]*'.
What to do: Many receivers are forgiving, but strict ones may ignore a file that does not match the schema. RadioDNS's SI tool (si.radiodns.org) can rebuild a correct file.
