Using python requests and internet header check tools I get 503 error with latest install .. Browsers do not complain, but the python monitor I built reports errors .. Anyone have an idea why ?
In my case the user agent is simple 'User-Agent': 'Mozilla/5.0 (compatible; Steelliberty-site-monitor/1.0; +https://www.steelliberty.net/mon.html😉'
The output below is from https://wtools.io/check-headers-online.
Site is specialforces.mypatriotsnetwork.com -- I have other sites on a subdomain with no issue.
